The magnitude of σ1 that will cause yielding according to the maximum-shear-stress theory is 9.94 ksi.

Yield stress for the zirconium-magnesium alloy, σY = 15.3 ksi

In-plane principal stresses are σ1 and σ2 = −0.54σ1

To find the maximum shear stress theory, the equation used is τ_max=1/2(σ1-σ2)

The maximum shear stress theory states that yielding begins when the maximum shear stress in a part equals or exceeds the shear strength of the material. It is represented as τ_max = τ_yield

Where τ_max is the maximum shear stress in a part and τ_yield is the shear strength of the material. In-plane principal stresses are σ1 and σ2 = −0.54σ1

Let us replace the value of σ2 in terms of σ1σ2 = −0.54σ1,σ1 = 1.85σ2

Substitute the values in the τ_max=1/2(σ1-σ2)

τ_max=1/2(σ1-(-0.54σ1))

τ_max=0.77σ1

Now, τ_yield= σY/2 = 7.65 ksi

Therefore, 0.77σ1 = 7.65

σ1 = 9.94 ksi

The methods used to seismically retrofit a building are: beam addition method, seismic wall addition method, support point adding method, and

seismic isolation method.

In construction of a building, seismically retrofitting or earthquake retrofitting is commonly done. The major reason to why it is done is to prevent displacement from the structure's foundation.

When seismically retrofitting is done, a building is considered safer and less likely to suffer damage when earthquake or any seismic forces strike.

So a retrofit is worth it as it will strengthen a building or an house against shake damage to help people living in it to remain safe and less worried. The following methods can therefore be used to provide a retrofit or to seismically retrofit a building:

Beam addition method

This is done by adding beams between the main girders of the existing reinforced concrete to improve the load carrying capacity of the reinforced concrete.

Seismic wall addition method

This is done by placing new reinforced concrete walls between existing ones and bonding them to improve load carrying capacity as a structural body

Support point adding method

This is done by supporting sections of beams and other existing concrete members with new members to reduce the span of members

Seismic isolation method

This is done by using seismic isolation bearings to reduce the seismic energy applied to the structure. This will improve the building's performance values during an earthquake.

Both technicians are correct, as the basecoat can be applied directly over a self-etching primer, and the acid in the primer will neutralize as it dries.

Applying a basecoat directly over a self-etching primer is a common practice in auto body repair. Self-etching primers contain an acid that helps to etch the surface of the metal, creating a better bond for the basecoat. As the primer dries, the acid neutralizes, leaving a strong bond between the primer and the basecoat. This ensures that the basecoat will adhere properly and provide a durable finish.

If the function is called with a single parameter of 50, the resulting iterable will include integers from 0 through 49, inclusive.

In most programming languages, when specifying a range or interval, the starting value is inclusive, while the ending value is exclusive. This means that the range will include all values starting from the initial value and ending one element before the specified end value.

In this case, since the parameter is 50, the function will generate an iterable that includes integers starting from 0 and ending at 49 (inclusive). The number 50 will not be included in the resulting iterable.

It is important to clarify the behavior of the function, especially when dealing with range or interval operations, as the inclusivity or exclusivity of the start and end values can affect the expected output.

By specifying that the range is inclusive for 0 through 49, it ensures that all integers within that range will be included in the resulting iterable, while excluding the value of 50.

Answer:

5 rad/sec

0.796 Hz

1.256 seconds

Explanation:

Y(t) = 23sin5t ----1

Y(t) = aSin(w)t----2

w = 5 rad/sec

Then we get the Oscillation frequency from the formula below

w = 2πf

We make f to be the subject of this formula

f = w/2π

f = 5/2*3.24

f = 5/6.28

f = 0.796Hz

From the calculated frequency, we get the period = 1/f

COP = 4.846

Explanation:

From the table A-11 i attached, we can find the entropy for the state 1 at -12°C.

h1 = 243.3 KJ/Kg

s1 = 0.93911 KJ/Kg.K

From table A-12 attached we can do the same for states 3 and 4 but just enthalpy at 800 KPa.

h3 = h4 = hf = 95.47 KJ/Kg

For state 2, we can calculate the enthalpy from table A-13 attached using interpolation at 800 KPa and the condition s2 = s1. We have;

h2 = 273.81 KJ/Kg

The power would be determined from the energy balance in state 1-2 where the mass flow rate will be expressed through the energy balance in state 4-1.

W' = m'(h2 - h1)

W' = Q'_L((h2 - h1)/(h1 - h4))

Where Q'_L = 150 kW

Plugging in the relevant values, we have;

W' = 150((273.81 - 243.3)/(243.3 - 95.46))

W' = 30.956 Kw

Formula foe COP is;

COP = Q'_L/W'

COP = 150/30.956

COP = 4.846

This question is incomplete, the complete question is;

An air-standard Diesel cycle engine operates as follows: The temperatures at the beginning and end of the compression stroke are 30 °C and 700 °C, respectively. The net work per cycle is 590.1 kJ/kg, and the heat transfer input per cycle is 925 kJ/kg. Determine the a) compression ratio, b) maximum temperature of the cycle, and c) the cutoff ratio, v3/v2.

Use the cold air standard assumptions.

Answer:

a) The compression ratio is 18.48

b) The maximum temperature of the cycle is 1893.4 K

c) The cutoff ratio, v₃/v₂ is 1.946

Explanation:

Given the data in the question;

Temperature at the start of a compression T₁ = 30°C = (30 + 273) = 303 K

Temperature at the end of a compression T₂ = 700°C = (700 + 273) = 973 K

Net work per cycle \(W_{net\) = 590.1 kJ/kg

Heat transfer input per cycle Qs = 925 kJ/kg

a) compression ratio;

As illustrated in the diagram below, 1 - 2 is adiabatic compression;

so,

Tγ\(^{Y-1\) = constant { For Air, γ = 1.4 }

hence;

⇒ V₁ / V₂ = \((\) T₂ / T₁ \()^{\frac{1}{Y-1}\)

so we substitute

⇒ V₁ / V₂ = \((\)  973 K / 303 K  \()^{\frac{1}{1.4-1}\)

= \((\)  3.21122  \()^{\frac{1}{0.4}\)

= 18.4788 ≈ 18.48

Therefore, The compression ratio is 18.48

b) maximum temperature of the cycle

We know that for Air, Cp = 1.005 kJ/kgK

Now,

Heat transfer input per cycle Qs = Cp( T₃ - T₂ )

we substitute

925 = 1.005( T₃ - 700 )

( T₃ - 700 ) = 925 / 1.005

( T₃ - 700 ) = 920.398

T₃ = 920.398 + 700

T₃ = 1620.398 °C

T₃ = ( 1620.398 + 273 ) K

T₃ = 1893.396 K ≈ 1893.4 K

Therefore, The maximum temperature of the cycle is 1893.4 K

c)  the cutoff ratio, v₃/v₂;

Since pressure is constant, V ∝ T

So,

cutoff ratio S = v₃ / v₂  = T₃ / T₂

we substitute

cutoff ratio S = 1893.396 K / 973 K

cutoff ratio S = 1.9459 ≈ 1.946

Therefore, the cutoff ratio, v₃/v₂ is 1.946

The center of gravity, also known as the balance point or point of rotation when an object is permitted to freely rotate, is the average location of an object's weight.

All objects with mass are attracted to one another by the gravitational attraction, which has a magnitude that is directly proportional to the masses of the two objects and inversely proportional to the square of their distance from one another.

By means of gravity, a planet or other body pulls items toward its core. All the planets are maintained in their orbits around the sun by the force of gravity.

Any particle of matter in the universe will gravitate toward any other with a force that varies directly as the product of the masses and inversely as the square of the distance between them, according to Newton's law of gravity.

In order to achieve the shortest distance from starting vertex (A) to F on a network, utilize Dijkstra's algorithm following these steps:

Initiate every vertex with a tentative distance value: assign zero to the starting point and infinity to other vertices.

Establish the initiating vertex as the current vertex.

Analyze all neighboring vertices of the current vertex and determine their respective tentative path length via current vertex. Proceed to compare it with its already assigned value; upgrade such distance if shorter than before.

Subsequent to analyzing adjacent points of the present node, designate it as 'visited'. Futuristic reference will disregard this chosen and visited vertex altogether.

Examine unexplored vertices marked as having the most reduced tentative distances, declare them 'current' while formulating new calculations for other contenders until pertinent conclusion is reached.
