Give snapshots of memory after each pass of the odd-even sort,
for the list {3, 9, 8, 1, 2, 5, 7, 6, 4}. In your snapshots
indicate which processors are comparing/swapping which
elements.

Answers

Answer 1

The Odd-Even Sort algorithm is applied to the list {3, 9, 8, 1, 2, 5, 7, 6, 4}. After each pass, the snapshots of memory show the comparison and swapping of elements between processors. The algorithm proceeds until the list is sorted in ascending order.

1st Pass:

Comparisons: Processors 1 and 2 compare elements 3 and 9, 8 and 1, 2 and 5, 7 and 6.Swaps: Processors 1 and 2 swap elements 9 and 3, 8 and 1, 5 and 2, 7 and 6.Snapshot: {9, 3, 1, 8, 2, 5, 7, 6, 4}

2nd Pass:

Comparisons: Processors 1 and 2 compare elements 9 and 1, 3 and 8, 2 and 5, 7 and 6.Swaps: Processors 1 and 2 swap elements 9 and 1, 8 and 3, 5 and 2, 7 and 6.Snapshot: {9, 1, 3, 8, 2, 5, 7, 6, 4}

3rd Pass:

Comparisons: Processors 1 and 2 compare elements 9 and 3, 1 and 8, 2 and 5, 7 and 6.Swaps: Processors 1 and 2 swap elements 9 and 3, 8 and 1, 5 and 2, 7 and 6.Snapshot: {9, 3, 1, 8, 2, 5, 7, 6, 4}

4th Pass:

Comparisons: Processors 1 and 2 compare elements 9 and 1, 3 and 8, 2 and 5, 7 and 6.Swaps: Processors 1 and 2 swap elements 9 and 1, 8 and 3, 5 and 2, 7 and 6.Snapshot: {9, 1, 3, 8, 2, 5, 7, 6, 4}

5th Pass:

Comparisons: Processors 1 and 2 compare elements 9 and 1, 3 and 8, 2 and 5, 7 and 6.Swaps: Processors 1 and 2 swap elements 9 and 1, 8 and 3, 5 and 2, 7 and 6.Snapshot: {9, 1, 3, 8, 2, 5, 7, 6, 4}

6th Pass:

Comparisons: Processors 1 and 2 compare elements 9 and 1, 3 and 8, 2 and 5, 7 and 6.Swaps: Processors 1 and 2 swap elements 9 and 1, 8 and 3, 5 and 2, 7 and 6.Snapshot: {9, 1, 3, 8, 2, 5, 7, 6, 4}

After the 6th pass, the list remains unchanged, indicating that it is sorted in ascending order. The Odd-Even Sort algorithm compares and swaps elements between processors based on their indices in an alternating pattern until no further swaps are needed, resulting in a sorted list.

A) The amount of space must be left between adjacent rails if they are just to touch on a summer day when their temperature is 31.0 °C is; 0.6048 cm

B) The stress in the rails on a summer day when their temperature is 31.0 °C is; 86.4 × 10⁶ Pa

Linear Thermal Expansion

We are given;

Length; L = 14 m

Initial Temperature; T_i = −5 °C

Final Temperature; T_f = 31 °C

The formula for Linear Thermal Expansion is;

ΔL = L_i * α * ΔT

where;

L_i is initial length

α is thermal expansion

ΔL is change in length

ΔT is change in temperature

Now, the thermal expansion of steel from online tables is α = 1.2 × 10⁻⁵ C⁻¹

Thus;

ΔL = 14 * 1.2 × 10⁻⁵  * (31 - (-5))

ΔL = 6.048 × 10⁻³ m = 0.6048 cm

The formula to get the stress is;

σ = Y * α  * ΔT

where;

Y is young's modulus of steel = 20 × 10¹⁰ Pa

α is thermal expansion

ΔT is change in temperature

Thus;

σ = 20 × 10¹⁰ × 1.2 × 10⁻⁵ × (31 - (-5))

σ = 86.4 × 10⁶ Pa

The complete question is;

Steel train rails are laid in 14.0-m long segments placed end to end. The rails are laid on a winter day when their temperature is −5 °C.

Process 1–2 occurs at constant volume until the temperature is 100°F. The second process, from state 2 to state 3, occurs at constant temperature, with Q23 = –98.9 Btu, until the quality is again 100%. Kinetic and potential energy effects are negligible. For 2.2 lb of ammonia, determinea) the heat transfer for Process 1–2, in Btu. b) the work for Process 2–3, in Btu.

Answers

Answer:

The heat transfer \(\mathbf{\mathbf{Q_{1-2}} = 35.904 \ Btu}\)

\(W_{2-3}= -71.312 \ Btu\)

Explanation:

At the initial state when P₁ = 10 lbf/in :

We obtain the internal energy u₁ and specific volume v₁.

u₁ = \(u_g\) = 574.08 btu/lbm

v₁ = \(v_g\)  = 2.4746  ft³/lbm

Process 1–2 occurs at constant volume until the temperature is 100°F.

i.e T₂ = 100⁰ F

At T₂ = 100⁰ F  : v₁ = v₂ = 2.4746  ft³/lbm  

\(\mathbf{u_2 = 591.28 + \dfrac{2.4746-2.5917}{2.117-2.5917}*(587.68 -591.28)}\)

\(\mathbf{u_2 = 591.28 + 0.246682115(-3.6)}\)

\(\mathbf{u_2 = 591.28+ (-0.888055614)}\)

\(\mathbf{u_2 \approx 590.4 \ btu/lbm}\)

\(\mathbf{Q_{1-2}= W+ \Delta U}\)

\(\mathbf{Q_{1-2}= W+m( u_2 -u_1)}\)

\(\mathbf{\mathbf{Q_{1-2}} = 0+2.2(590.4-574.08)}\)

\(\mathbf{\mathbf{Q_{1-2}} = 0+2.2(16.32)}\)

\(\mathbf{\mathbf{Q_{1-2}} = 35.904 \ Btu}\)

b) the work for Process 2–3, in Btu.

At \(T_3 = 100 ^0 \ F\) ; \(u_3 = 577.86 \ Btu/lbm\)

\(Q_{2-3} = W_{2-3} + \Delta U\)

\(Q_{2-3} = W_{2-3} + m(u_3-u_2)\)

\(Q_{2-3} = W_{2-3} +2.2(577.86-590.4)\)

\(-98.9 = W_{2-3} +2.2(577.86-590.4)\)

\(-W_{2-3}= 2.2(577.86-590.4)+98.9\)

Brief overview of replacement and displacement deep foundations and with illustrations Please?

Answers

Deep foundations are used when the surface soils are not capable of supporting the loads of a structure. Two common types of deep foundations are replacement and displacement foundations.

1. Replacement foundations:

Replacement foundations are created by removing the soil beneath a structure and replacing it with concrete or other materials. This creates a solid, stable foundation that can support the weight of the structure.

Illustration: The process of creating a replacement foundation begins by excavating the soil beneath the structure, leaving a large hole. The hole is then filled with concrete, which is allowed to cure and harden. The concrete provides a solid base for the structure to rest on, ensuring that it is stable and secure.

2. Displacement foundations:

Displacement foundations work by pushing soil aside as they are installed, creating a cavity in the ground that is then filled with concrete. These foundations are often used when soil conditions are too difficult to excavate or when a more efficient installation method is desired.

Illustration: The process of creating a displacement foundation involves driving a steel pile or tube into the ground. The pile is typically filled with concrete as it is being driven, creating a cavity in the soil. Once the pile has reached the desired depth, it is left in place, and the cavity is filled with concrete. This creates a solid, stable foundation that can support the weight of the structure.

In summary, both replacement and displacement deep foundations are effective methods for creating stable foundations for structures when the soil conditions are not suitable for shallow foundations. The choice of foundation type depends on the specific site conditions, load requirements, and project budget.

La probabilidad de que un nuevo producto tenga éxito es de 0.85. Si se eligen 10 personas al azar y se les pregunta si comprarían el nuevo producto, ¿cuál es la probabilidad de que por lo menos 8 adquieran el nuevo producto?

Answers

Answer:

La probabilidad pedida es \(0.820196\)

Explanation:

Sabemos que la probabilidad de que un nuevo producto tenga éxito es de 0.85. Sabemos también que se eligen 10 personas al azar y se les pregunta si comprarían el nuevo producto. Para responder a la pregunta, primero definiremos la siguiente variable aleatoria :

\(X:\) '' Número de personas que adquirirán el nuevo producto de 10 personas a las que se les preguntó ''

Ahora bien, si suponemos que la probabilidad de que el nuevo producto tenga éxito se mantiene constante \((p=0.85)\) y además suponemos que hay independencia entre cada una de las personas al azar a las que se les preguntó ⇒ Podemos modelar a \(X\) como una variable aleatoria Binomial. Esto se escribe :

\(X\) ~ \(Bi(n,p)\) en donde \(''n''\) es el número de personas entrevistadas y \(''p''\) es la probabilidad de éxito (una persona adquiriendo el producto) en cada caso.

Utilizando los datos ⇒ \(X\) ~ \(Bi(10,0.85)\)

La función de probabilidad de la variable aleatoria binomial es :

\(p_{X}(x)=P(X=x)=\left(\begin{array}{c}n&x\end{array}\right)p^{x}(1-p)^{n-x}\)    con \(x=0,1,2,...,n\)

Si reemplazamos los datos de la pregunta en la función de probabilidad obtenemos :

\(P(X=x)=\left(\begin{array}{c}10&x\end{array}\right)(0.85)^{x}(0.15)^{10-x}\) con \(x=0,1,2,...,10\)

Nos piden la probabilidad de que por lo menos 8 personas adquieran el nuevo producto, esto es :

\(P(X\geq 8)=P(X=8)+P(X=9)+P(X=10)\)

Calculando \(P(X=8), P(X=9)\) y \(P(X=10)\) por separado y sumando, obtenemos que \(P(X\geq 8)=0.820196\)

Por definición de variable aleatoria binomial, la probabilidad de que por lo menos 8 adquieran el nuevo producto es 0.8202.

En primer lugar, debes saber que la Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso.

En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles.

Por otro lado, una variable aleatoria es una función que asocia un número real, perfectamente definido, a cada punto muestral.

Una variable aleatoria es discreta si los números a los que da lugar son números enteros.

Finalmente, una distribución binomial es una distribución de probabilidad discreta que describe el número de éxitos al realizar n experimentos independientes entre sí, acerca de una variable aleatoria.

La expresión  para calcular la distribución binomial es:

P(X=x)=( \(n\\ x\) ) pˣ qⁿ⁻ˣ

Donde:

n = Número de ensayos/experimentos x = Número de éxitos p = Probabilidad de éxito q = Probabilidad de fracaso (1-p)

Recordar que:

( \(n\\ x\) )= \(\frac{n!}{x!(n-x)!}\)

donde el signo de exclamación representa el símbolo de factorial, es decir el producto de todos los números enteros positivos desde 1 hasta n.

En este caso, sabes que la probabilidad de que un nuevo producto tenga éxito es de 0.85 y se eligen 10 personas al azar. Entonces se define la siguiente variable aleatoria:

X= '' Número de personas que adquirirán el nuevo producto de 10 personas a las que se les preguntó ''

Suponiendo que hay independencia entre cada una de las personas al azar a las que se les preguntó, es posible usar una variable aleatoria Binomial. Siendo n el número de personas entrevistadas (en este caso, 10 personas) y p la probabilidad de éxito (una persona adquiriendo el producto, en este caso 0.85) en cada caso, la expresión a utilizar queda expresada como:

P(X=x)=( \(10\\ x\) ) 0.85ˣ (1-0.85)¹⁰⁻ˣ

P(X=x)= \(\frac{10!}{x!(10-x)!}\) 0.85ˣ (0.15)¹⁰⁻ˣ

Se desea calcular la probabilidad de que por lo menos 8 adquieran el nuevo producto. Siendo 10 las personas elegidas al azar, puede ser que sean 8,9 o 10 las personas que adquieran un nuevo producto. Entonces la probabilidad deseada es calculada como:

\(P(X\geq 8)= P(X=8) + P(X=9) + (P=10)\)

Entonces:

\(P(X\geq 8)=\)  \(\frac{10!}{8!(10-8)!}\) 0.85⁸ (0.15)¹⁰⁻⁸ +  \(\frac{10!}{9!(10-9)!}\) 0.85⁹ (0.15)¹⁰⁻⁹ +  \(\frac{10!}{10!(10-10)!}\) 0.85¹⁰ (0.15)¹⁰⁻¹⁰

Resolviendo:

\(P(X\geq 8)=\)  \(\frac{10!}{8!2!}\) 0.85⁸ (0.15)² +  \(\frac{10!}{9!1!}\) 0.85⁹ (0.15)¹ +  \(\frac{10!}{10!0!}\) 0.85¹⁰ (0.15)⁰

\(P(X\geq 8)=\)  45×0.85⁸×(0.15)² +  10×0.85⁹×(0.15)¹ +  1×0.85¹⁰×(0.15)⁰

\(P(X\geq 8)=\)  0.2759 +  0.3474 + 0.1969

\(P(X\geq 8)=\)  0.8202

Finalmente, la probabilidad de que por lo menos 8 adquieran el nuevo producto es 0.8202.

A parallel helical gearset consists of a 19-tooth pinion driving a 57-tooth gear. The pinion has a left-hand helix angle of 30°, a normal pressure angle of 20°, and a normal module of 2.5 mm.
Find:_______.
(a) The normal, transverse, and axial circular pitches
(b) The transverse diametral pitch and the transverse pressure angle
(c) The addendum, dedendum, and pitch diameter of each gear

Answers

Answer:

a)

normal circular pitch = 7.8539 mm

transverse circular pitch = 9.0689 mm

axial circular pitches = 15.7077

b)

transverse diametral pitch is 0.3464 teeth/mm

transverse pressure angle is 22.8°

c)

Addendum = 2.5 mm

dedendum = 3.125 mm

pinion diameter = 54.8482 mm and Gear diameter = 164.5448 mm

Explanation:

Given that;

module m = 2.5 mm

Number of teeth on Gear  nG = 57 TEETH

Number of teeth on Pinion  nP = 19 TEETH

Helix angle W = 30°

Normal Pressure angle β = 20°

finding the circular pitch

Pc = πm

we substitute

Pc = π * 2.5 mm = 7.8539 mm

now the diametral pitch p = π / Pc

= π / 7.8539

= 0.4 teeth/mm

a)

So the normal circular pitch

Pn = π / P

Pn = π / 0.4

Pn = 7.8539 mm

the transverse circular pitch

Pt = Pn / cosW

Pt = 7.8539 / cos30°

Pt = 9.0689 mm

for axial circular pitches

Px = Pt / tanW

Px = 9.0689 / tan30°

Px = 15.7077

b)

The transverse diametral pitch and the transverse pressure angle.

The transverse diametral pitch Pt = PcosW

= 0.4 * cos30°

= 0.3464 teeth/mm

transverse diametral pitch is 0.3464 teeth/mm

transverse pressure angle  β1 = tan^-1 ( tan βn / cos W)

=  tan^-1 ( tan20° / cos 30°)

= tan^-1 ( 0.42027 )

β1 = 22.8°

transverse pressure angle is 22.8°

c)

The addendum, dedendum, and pitch diameter of each gear

Now from table standard Tooth proportions for Helical Gears;

Addendum a = 1/p

= 1 / 0.4

= 2.5 mm

dedendum b = 1.25 / p

= 1.25 / 0.4

= 3.125 mm

now  pinion diameter dP = Np / PcosW

= 19 / 0.4 (cos30°)

= 54.8482 mm

Gear diameter dG = nG / pcosW

= 57 / 0.4 (cos30°)

= 164.5448 mm

to reduce the work diameter by .006 inch, the cross feed dial is rotated clockwise .003 inch. (True or False)

Answers

The given statement "to reduce the work diameter by .006 inch, the cross feed dial is rotated clockwise .003 inch" is true because this action effectively reduces the work diameter by the specified amount, in this case, .006 inch.

Is rotating the cross feed dial clockwise effective in reducing the work diameter?

To reduce the work diameter by .006 inch, the cross feed dial is rotated clockwise .003 inch. This statement is true. When machining, the cross feed is used to move the cutting tool perpendicular to the workpiece's axis.

By rotating the cross feed dial clockwise, the cutting tool moves towards the workpiece, which reduces the work diameter. This movement is equivalent to cutting a thin layer of material from the workpiece's surface.
