Two's complement is a mathematical operation that converts a positive binary number with equivalent value reversibly into a negative binary number with equivalent value.

it occurs using the binary digit with the greatest place value to indicate whether the binary number is positive or negative.

Consider each of those three cases' four sub-cases. There are two positives and two negatives, with one of each.

Demonstrate that some of the sub-cases are not feasible in each case. Then, for each sub-case, determine whether it indicates overflow.

Thus, by this it can be proved that in a 2’s complement number system addition overflows if and only if the carry from the sign position does not equal the carry into the sign position.

Answer:

the magnitude of the stress necessary to cause slip to occur on the (111) plane in the \([1 0 \overline 1]\) direction is 4.85 MPa

Explanation:

From the given information;

To determine the angle \(\phi\) between the direction [100] and [111]; we have:

\(\phi = cos ^{-1} [\dfrac{u_1u_2+v_1v_2+w_1w_2}{ \sqrt{(u_1^2+v_1^2+w_1^2) (u_2^2+v_2^2+w_2^2) }}}\)

where;

[u₁,v₁,w₁] and [u₂, v₂, w₂] are directional indices.

replacing 1 for u₁ , 0 for v₁ and 0 for w₁  ;

also replacing 1 for u₂, 1 for v₂ and  1 for w₂ ; we have :

\(\phi = cos ^{-1} [\dfrac{1*1+0*1+0*1}{ \sqrt{(1^2+0^2+0^2) (1^2+1^2+1^2) }}}\)

\(\phi = 54.7^0\)

To determine the angle \(\lambda\) for the slip direction \([1 0 \overline 1]\)

\(\lambda= cos ^{-1} [\dfrac{u_1u_2+v_1v_2+w_1w_2}{ \sqrt{(u_1^2+v_1^2+w_1^2) (u_2^2+v_2^2+w_2^2) }}}\)

replacing 1 for u₁ , 0 for v₁ and 0 for w₁  ;

also replacing 1 for u₂, 1 for v₂ and  -1 for w₂ ; we have :

\(\lambda = cos ^{-1} [\dfrac{1*1+0*0+(0*-1)}{ \sqrt{(1^2+0^2+0^2) (1^2+0^2+(-1^2)) }}}\)

\(\phi = cos ^{-1} [\dfrac{1}{\sqrt{2}}]\)

\(\lambda = 45^0\)

The yield strength  for the slip process \([1 0 \overline 1]\) can now be calculated as:

\(\sigma_x = \dfrac{t_{xr}}{cos \phi \ \ cos \lambda}\)

where

\(t_{xr}\) = 1.98 MPa

\(\sigma_x = \dfrac{1.98}{cos 54.7^0 \ \ cos 45}\)

\(\sigma_x = \dfrac{1.98}{0.5779 *0.7071}\)

\(\mathbf{\sigma _x = 4.85 \ MPa}\)

Hence, the magnitude of the stress necessary to cause slip to occur on the (111) plane in the \([1 0 \overline 1]\) direction is 4.85 MPa

Do not use I me my we. Less exclamation points, bigger words like "Pompous" Lots of uptight language, as if you are at an interview. structure should be precise and sharp, sharper than Angelina Jolie's cheekbones

Explanation:

Answer:

Median

Explanation:

Since the engineer is interested in the relative strength of machine parts made of two different metals. And after conducting her measurements, she learned that a small number of the plastic parts may have had cracks in them before testing, which would have caused them to break at ridiculously low force levels. Whereas, there was no possibility of cracked aluminum parts.

This small crack in the plastic part will affect the mean (average) value if it is used as a central tendency for comparison. This same thing will affect the mode and the range of the value of strength.

The best measure of central of tendency to use is median since the affected cracked part in the plastic is minimal.

The largest positive number that can be represented in 13 bits for the two cases are

A) Unsigned number

\((2)^n - 1 = (2)^{13} - 1 = 8191\)

In Binary - \((1111111111111)_2\)

In decimal - \((8191)_{10}\)

In hexadecimal - \((1FFF)_{16\)

B) Signed number

\(2^n = 2^{13} = 8192\)

The range is from \((2^n-1)\)

therefore, the maximum value is \((4096)_{10}\)

In binary - \((1000000000000)_2\)

In hexadecimal - \((1000)_{16}\)

When lamps are connected in series to a battery, the brightness of each lamp decreases. This is due to the nature of a series circuit and the principles of electrical current flow.

In a series circuit, the components (in this case, lamps) are connected one after another in a single path. This means that the same current flows through each lamp in the circuit. When lamps are connected in series, the total resistance in the circuit increases because the individual resistances of the lamps add up. As a result, the current flowing through the circuit remains the same, but it gets divided among the lamps.

According to Ohm's Law, the brightness of a lamp is directly proportional to the current passing through it. Therefore, as the current is divided among multiple lamps connected in series, each lamp receives a smaller portion of the total current. This reduced current results in a decrease in the brightness of each lamp.

Additionally, lamps have a certain operating voltage, which is the voltage required to produce their optimal brightness. In a series circuit, the total voltage of the battery is distributed across the lamps. As more lamps are added in series, the voltage available for each lamp decreases. Consequently, the lamps operate at a lower voltage than their optimal level, leading to a further decrease in brightness.

It's important to note that this explanation assumes the lamps have the same resistance and are designed to operate under the same voltage. If the lamps have different resistances or are designed for different voltages, the brightness may be affected differently.

Answer:

the theoretical fracture strength of the brittle material is 5.02 × 10⁶  psi

Explanation:

Given the data in the question;

Length of surface crack α = 0.25 mm

tip radius ρ\(_t\) = 1.2 × 10⁻³ mm

applied stress σ₀ = 1200 MPa

the theoretical fracture strength of a brittle material = ?

To determine the the theoretical fracture strength or maximum stress at crack tip, we use the following formula;

σ\(_m\) = 2σ₀\((\) α / ρ\(_t\) \()^{\frac{1}{2}\)

where α is the Length of surface crack,

ρ\(_t\) is the tip radius,

and σ₀ is the applied stress.

so we substitute

σ\(_m\) = (2 × 1200 MPa)\((\) 0.25 mm / ( 1.2 × 10⁻³ mm ) \()^{\frac{1}{2}\)

σ\(_m\) = 2400 MPa × \((\) 208.3333 \()^{\frac{1}{2}\)

σ\(_m\) = 2400 MPa × 14.43375

σ\(_m\) = 34641 MPa

σ\(_m\) = ( 34641 × 145 )psi

σ\(_m\) = 5.02 × 10⁶  psi

Therefore, the theoretical fracture strength of the brittle material is 5.02 × 10⁶  psi

Explanation:

A faulty vacuum booster can actually affect the operation of an engine. Engine stalls when brakes are applied. And this can happen when the diaphragm that is inside the brake booster fails. The failing thus allows air to bypass the seal. When the brakes are then pressed, the engine will actually feel like it will stall, and the idle will most probably drop. Also, asides a reduction in the break performance quality, a stalling engine is very bad and can result to many negative effects.

Plastic and composite fenders require different bolts because fenders combine energy absorption and deflection qualities.

Plastics are defined as a class of substances, either artificial or natural, that can be molded while still soft and subsequently hardened to maintain the desired shape. The thickness grade for plastic sheeting most frequently used is 6 mil. This is 0.006 inch, or six thousandths of an inch.

Fasteners are regarded as tools that are used in a variety of applications to form a solid junction. While some fasteners are permanently linked, the majority allow joints to be broken apart or withdrawn without harming the pieces that were joined.

Answer:

To calculate M2, p2, and T2 at the exit of the combustor, we can use the isentropic relations for a nozzle, assuming that the flow through the combustor is adiabatic and isentropic.

Using the isentropic relations, we can relate the Mach number, pressure, and temperature at the exit of the combustor to their values at the inlet of the combustor.

M2 = sqrt((2/(gamma-1))*((T1/(1+((gamma-1)/2)*M1^2))*(1+((gamma-1)/2)*M1^2*0.5*(gamma+1)*0.5*(1+0.5*(gamma-1)*M1^2)^(-1)*(1-0.5*(gamma-1)*M1^2*0.5*(gamma+1)*0.5*(1+0.5*(gamma-1)*M1^2)^(-1)*(1+0.5*(gamma-1)*M1^2*0.5*(gamma+1)*0.5*(1+0.5*(gamma-1)*M1^2)^(-1)*((gamma+1)/(2*gamma))^((gamma+1)/(2*(gamma-1))))))^(-1))

where gamma = 1.4 is the specific heat ratio of the fuel-air mixture.

Substituting the given values, we get:

M2 = sqrt((2/(1.4-1))*((570/(1+((1.4-1)/2)*0.4^2))*(1+((1.4-1)/2)*0.4^2*0.5*(1+0.5*(1.4-1)*0.4^2)^(-1)*(1-0.5*(1.4-1)*0.4^2*0.5*(1+0.5*(1.4-1)*0.4^2)^(-1)*(1+0.5*(1.4-1)*0.4^2*0.5*(1+0.5*(1.4-1)*0.4^2)^(-1)*((1.4+1)/(2*1.4))^((1.4+1)/(2*(1.4-1))))))^(-1)) = 0.818

Answer:

115 Ib/ft^3

Explanation:

To determine the maximum dry density in Ib/ft3 we have to calculate :

Bulk unit weight ( yb ) ; W / v

Dry unit weight ( yd. ) :  yb / ( 1 + w )

For every set of data given

assuming  v = 1/30 ft^3

calculating for the 3 data set ( maximum dry density )

weight of soil (W) = 4.40

moisture content (%) (w) = 15.0 = 0.15

Bulk unit weight (yb) = 4.40 / (1/30)  = 132 Ib/ft^3

Dry unit weight ( yd. ) = 132 / ( 1 + 0.15 ) = 114.702 Ib/ft^3

The FBD (Free Body Diagram) that is required to determine the internal forces at point J should include all external forces acting on the system and any reactions or forces present at point J.

This FBD will allow for the determination of the internal forces, such as shear forces and bending moments, at point J.
To determine the internal forces at point J, you need to draw a Free Body Diagram (FBD). In this FBD, you should include all the external forces acting on the object at point J, such as gravitational force, tension, friction, and any applied forces. Once you have drawn the FBD, you can use equilibrium equations (sum of forces in horizontal and vertical directions equals zero) to solve for the unknown internal forces. After finding the internal forces at point J, you can move on to the next part of your problem. Forces are physical quantities that describe the interactions between objects or systems. They can cause a change in motion or deformation in an object. Some common types of forces include gravitational force, electromagnetic force, frictional force, and normal force. Forces can be described by their magnitude, direction, and point of application. Newton's laws of motion provide a framework for understanding the behavior of objects under the influence of forces. Understanding forces is essential in many fields, including physics, engineering, and biomechanics, as it allows for the prediction and control of the behavior of systems under different conditions.

This question is incomplete, the missing diagram is uploaded along this answer below;

Answer:

the speed Vc of the current and its direction measured clockwise from the north is 0.71 m/s and 231.02° respectively

Explanation:

Given the data in the question and as illustrated in the diagram below;

The absolute velocity of the ship Vs is 6 Knots due east

so we convert to meter per seconds

Vs = 6 Knots × \(\frac{0.51444 m/s}{1 Knots}\) = 3.0866 m/s

Next we determine the relative velocity of the ship Vs/c

Vs/c = AB / t

given that distance between A to B = 10 nautical miles which requires 2 hours

so we substitute

Vs/c = 10 nautical miles / 2 hrs

Vs/c = [10 nautical miles × \(\frac{1852 m}{1 nautical-miles}\) ] / [ 2 hrs × \(\frac{3600s}{1hr}\) ]

Vs/c = 18520 / 7200

Vs/c = 2.572 m/s

Now, from the second diagram below, { showing the relative velocity polygon }

Now, using COSINE RULE, we calculate the velocity current.

Vc = √( V²s + V²s/c - 2VsSs/ccos10 )

we substitute

Vc = √( (3.0866)² + (2.572)² - (2 × 3.0866 × 2.572 × cos10 ) )

Vc = √( (3.0866)² + (2.572)² - (2 × 3.0866 × 2.572 × 0.9848 ) )

Vc = √( 9.527099 + 6.615184 - 15.6361 )

Vc = √0.506183

Vc = 0.71 m/s

Next, we use the SINE RULE to calculate the direction;

Vc/sin10 = Vs/c / sinθ

we substitute

0.71 / sin10 = 2.572 / sinθ

0.71 / 0.173648 = 2.572 / sinθ

4.0887 = 2.572 / sinθ

sinθ  = 2.572 / 4.0887

sinθ = 0.62905

θ = sin⁻¹( 0.62905 )

θ = 38.98°

So, angle measured clock-wise will be;

θ = 270° - 38.98°

θ = 231.02°

Therefore, the speed Vc of the current and its direction measured clockwise from the north is 0.71 m/s and 231.02° respectively
