Explanation: made more sense

The elastic properties of the brass specimen enables it to return to its

original length when stressed below the yield strength.

The correct responses are;

4. a. The final length is 90.0 m.

b. The final length is 97.2 mm.

Reasons:  

a. Diameter of the brass alloy = 7.5 mm

Length of the specimen = 90.0 mm

Force applied = 6000 N

The equation for the applied stress, σ, is presented as follows;

\(\sigma = \dfrac{Force \ applied}{Area \ of \ specimen} = \dfrac{6000 \, N}{\pi \cdot \left(\dfrac{7.5 \times 10^{-3}}{2} \, m} \right)^2 } \approx 135.81 \ \mathrm{MPA}\)

Depending on the cold working condition, 135.81 MPa is below the yield

strength, and the brass will return to its original condition when the force is

removed. The final length is remains as 90.0 m.

b. When the applied force is F = 16,500 N, we have;

\(\sigma = \dfrac{16,500\, N}{\pi \cdot \left(\dfrac{7.5 \times 10^{-3}}{2} \, m} \right)^2 } \approx 373.48\ \mathrm{MPA}\)

The stress found for the force of 16,500 N is above the yield stress of

brass, and it is therefore, in the plastic region.

From the stress strain curve, the strain can be estimated by drawing a line

from the point of the 373.48 MP on the stress strain curve, parallel to the

elastic region to intersect the strain axis, which gives a value of strain

approximately, ε = 0.08.

The length of the specimen is given by the formula; \(l_i = l_0 \cdot (1 + \epsilon)\)

Therefore;

\(l_i\) = 90 × (1 + 0.08) = 97.2

The final length of the specimen, \(l_i\) = 97.2 mm

Answer:

Option 2, In seismic areas, the most crucial requirement for precast concrete is to tie elements together laterally

Explanation:

In seismic areas, the in-plane lateral  forces are very larger and hence in order to restrict the lateral movement governed by the lateral force, lateral ties are essential .

Specific design detailing such as interior and  perimeter ties in the floors causes diaphragm behavior and hence distribute the load evenly without any movement.

Hence, option 2 is correct

The frequency of the AC supply is 0.036 Hz.

We know that an alternating current circuit is the kind of circuit in which we do have the resistor in addition to the to the capacitor or the inductor or both as the case may be.

Here we are told that; A 32x10^-6 F capacitor is connected to a 60V AC supply in series with a 56 ohm resistor. The current flowing in the circuit is 0.16 A.

We can tell that the impedance of the circuit can be obtained by the use of the formula;

V = IZ

V = voltage

I = current

Z = impedance

Z = V/I

Z = 60 V/0.16 A

Z = 375 ohms

Then we have;

Z = √R^2 - XC^2

375 = √(56)^2 - (1/2 * 3.142 * f *  32x10^-6)^ 2

140625 = 3136 - (1/2 * 3.142 * f *  32x10^-6)^ 2

140625 -  3136  =  (1/2 * 3.142 * f *  32x10^-6)^ 2

137489 = 1/2 * 10^-4 f

A dispersion strengthened composite but not for a precipitation hardened alloy. At room temperature, they are not as potent.

They are more resistant to creep. Since they don't coarsen at high temperatures, they are more effective. Typically, they are oxide particles. A heat treatment technique known as precipitation hardening, also known as age hardening or particle hardening, is used to increase the yield strength of malleable materials, such as the majority of structural alloys made of aluminium, magnesium, nickel, and titanium as well as some steels and stainless steels. Precipitation-strengthening of an alloy system requires the presence of a terminal solid solution with a decreasing solid solubility with decreasing temperature. Solution treatment, quenching, and ageing are the three fundamental processes in the precipitation-hardening process.

b)  482.6 MPa

Explanation:

Gauge length = 50 mm

Tensile load = 1032 N

extension of gauge length = 0.625 mm

Extent of load sustainable by sample = 2063 N

Assuming a cross section area = 2500 mm^2 = 0.0025 m^2

a) Determine the Elastic modulus of the Polymer

Elastic modulus = stress / strain  --------  ( 1 )

  = ( f/A / strain )

f/A = force / area = 1032 / 0.0025 m^2  = 4.128 * 10^5 N/m^2

strain = Δl / original l  = 0.625 / 50 = 0.0125

The resultant force will be F = 6i-j-14k , Therefore f1 and f2 are in cartesian form.

The coordinates of the Free-body diagram points are given as

0=(0,0,0) m

A=(0.15,0,0.3) m

B=(0,-0.25,0.3) m

Therefore the position vector of OA will be.

roa = (0.15-0)i +(0-0)j +(0.3–0)k

= 0.15i +0j +0.3k

Then the position vector of OB,

rob =(0-0)i +(-0.25 - 0); +(0.3–0)k

= 0i -0.25j +0.3K

So,

The equivalent resultant force can be expressed as,

F = F1+ F2

By substituting,

6i - 3j -10k for  F1, and 2j -4K for F2.

F =6i -3j -10k +2j - 4k

A caisson is a watertight enclosure that can be pumped dry so that construction activities, such as the construction of piers can take place. A caisson is a watertight structure or chamber, usually made of wood, metal, or concrete, that is sunk to the bed of a river, lake, or ocean to provide a foundation or support for a bridge, building, or other structure.

A caisson is constructed onshore and then floated to the location where it is to be sunk into the water. Once in place, water is pumped out of the caisson, and construction workers enter the dry chamber to begin work on the foundation or support structure. The use of caissons has been an important development in the construction of bridges and other structures in areas with deep water or unstable soils.

A foundation called a caisson is used in construction on soft or deep water. It involves filling a series of large, watertight cylinders with concrete and sinking them into the ground. The base serves as a solid foundation for any subsequent structures. The construction of large structures like bridges, docks, and caissons is common.

The theoretical volume flow rate through the venturi meter can be calculated by using the Bernoulli's equation, principle of continuity, and given pressure difference and diameters.

To calculate the theoretical volume flow rate through the venturi meter, we can use the Bernoulli's equation and the principle of continuity.

First, we need to determine the velocity at the throat of the venturi meter. Since the flow is incompressible, the equation of continuity tells us that the velocity at the throat is inversely proportional to the area of the throat.

Using the formula for the area of a circle (A = πr²), we can find the ratio of the areas of the throat (A₂) to the pipeline (A₁): A₂/A₁ = (d₂/2)² / (d₁/2)²

Substituting the given diameters, we get: A₂/A₁ = (100/250)² = 0.16

From Bernoulli's equation, we know that the pressure difference (ΔP) is related to the velocity difference (ΔV) as: ΔP = ρ/2 * (ΔV)², where ρ is the density of the fluid.

We can rearrange this equation to solve for ΔV: ΔV = √(2 * ΔP / ρ)

Given that the pressure difference is 0.63 m of mercury and the specific gravity of oil is 0.9 (which implies ρ = 0.9 * ρ_water), we can calculate the velocity difference at the throat.

Next, we can use the principle of continuity to relate the velocity at the throat (V₂) to the theoretical volume flow rate (Q): Q = A₂ * V₂

By substituting the known values, including the calculated velocity difference, we can determine the theoretical volume flow rate through the venturi meter.
