Uncertainty analysis at the design stage refers to a preliminary analysis carried out before the measurement.

The causes of error that affect a measurement cannot be provided by design stage uncertainty analysis, but it can provide information and evaluate methods for instrument selection.

The precision and accuracy of the measuring device, as well as any other elements that can impair the experimenter's capacity to make the measurement, serve to restrict the uncertainty of a single measurement, and it is the experimenter's responsibility to calculate the uncertainty.

Zero-Order Uncertainty is a prediction of the anticipated uncertainty resulting from reading the data (interpretation error or quantization error). This fault is thought to be smaller than the instrumentation error.

1. We can see here that three phase refers to a type of electrical power transmission that uses three alternating current (AC) waveforms that are 120 degrees out of phase with each other. This is different from single-phase power transmission, which uses only one AC waveform.

Voltage, also known as electric potential difference, is a measure of the electrical potential energy per unit of charge in an electrical circuit. It is defined as the amount of work required to move a unit of electric charge between two points in a circuit, typically measured in volts (V).

Three-phase power is needed because it allows for more power to be transmitted over a given amount of wire or cable. With three-phase power, the power is delivered in a more consistent manner, which means that there is less voltage drop over long distances.

2. In order for a three-phase system to be balanced, the three phases must have the same amplitude and be 120 degrees out of phase with each other. The voltage equation of a balanced three-phase voltage source is given by:

Vph = Vline / √3

where Vph is the phase voltage and Vline is the line voltage. The phasor diagram for a balanced three-phase system shows three sinusoidal waveforms that are displaced by 120 degrees from each other.

Technician B only is correct. Technician B only removes the spark plug for the cylinder he is testing.

When preparing for a compression test, it is necessary to disable the ignition system. This prevents the engine from starting during the test, allowing accurate measurement of the cylinder's compression. Technician A is correct in disabling the ignition system, which typically involves disconnecting the spark plug wires or using a specific ignition system disabling tool.

However, Technician B, who only removes the spark plug for the cylinder being tested, is not following the correct procedure. To obtain accurate compression readings, it is essential to remove all spark plugs from the engine. This ensures that there is no combustion happening in any of the cylinders, allowing the compression tester to measure the maximum pressure within each cylinder without interference from the ignition system.

Therefore, only Technician A is correct in disabling the ignition system, while Technician B should also remove all spark plugs before conducting the compression test.

When a dielectric is inserted into a capacitor connected to a battery, the energy stored in the capacitor increases. This is because the electric field between the plates decreases due to the presence of the dielectric, which leads to an increase in capacitance and an increase in energy stored in the capacitor.

The capacitance is defined as the ability of a capacitor to store energy in the form of an electric charge, and it is directly proportional to the distance between the plates and inversely proportional to the dielectric constant of the medium between the plates.

The work done in the process of inserting a dielectric into a capacitor is given by the equation W = Fd, where W is the work done, F is the force required to insert the dielectric, and d is the distance over which the force is applied. The force required to insert the dielectric is proportional to the change in electric field between the plates, which in turn is proportional to the dielectric constant of the medium.

The energy stored in a capacitor connected to a battery increases when a dielectric is inserted, and the work done in the process depends on the dielectric constant of the medium.

Answer:

A) σ_y = 79096 lb/in² = 79.1 ksi

B) strain-hardening exponent = 0.102

(strength coefficient = 137838.78 lb/in²

Explanation:

A) Formula for volume is;

V = πd²h/4

We are given;

height 2.0 in and diameter 1.5 in

Thus;

V = (π × 1.5² × 2)/4

V = 3.53 in³

Area is;

A = πd²/4

A = (π × 1.5²)/4

A = 1.77 in²

Yield strength is gotten from the formula;

σ_y = Force/Area

We are given load = 140,000 lb

Thus;

σ_y = 140000/1.77

σ_y = 79096 lb/in²

B) We are given

modulus of elasticity: E = 30 × 10^(6) lb/in²

Formula for strain is;

ε = σ_y/E

ε = 79096/(30 × 10^(6))

ε = 0.00264

The metal yields (0.2% offset), thus;

strain offsets = 0.00264 + 0.002

strain offsets: ε1 = 0.00464

Thus;

(h_i - h_o)/h_o = 0.00464

(h_i/h_o) - 1 = 0.00464

(h_i/h_o) = 1.00464

h_i = h_o(1.00464)

h_o = 2 in

Thus; h_i = 2(1.00464) = 2.00928 in

Area = Volume/height = 3.53/2.00928 = 1.757 in²

True stress is;

σ = force/area = 140000/1.757

σ1 = 79681.27 lb/in²

At a load of 260,000 lb, the height has been reduced to 1.6 in. Thus;

Area = 3.53/1.6 = 2.206 in²

True stress is;

σ2 = 260000/2.206

σ2 = 117860.38 lb/in²

True strain;

ε2 = In(2/1.6)

ε2 = 0.223

From flow curve;

σ = kεⁿ

Thus;

σ1 = k(ε1)ⁿ

79681.27 = k(0.00464ⁿ) - - - (eq 1)

Also for σ2 = k(ε2)ⁿ;

117860.38 = k(0.223ⁿ) - - - - - (eq 2)

From eq 1,

k = 79681.27/0.00464ⁿ

Putting this for k in eq2 to get;

117860.38 = (0.223ⁿ) × 79681.27/0.00464ⁿ

117860.38/79681.27 = 0.223ⁿ/0.00464ⁿ

Solving for n, we have ≈ 0.102

Thus,K is;

k = 79681.27/0.00464^(0.102)

k = 137838.78 lb/in²

Soil is a vital component of any construction process. It is used to provide a strong and stable foundation that can support the weight of the structure built on top of it. Soil needs to be compacted to its optimum bulk density of 2 gm/cc at 15% moisture content (mass basis) for an earthen dam structure.

If the soils are initially at 10% moisture content (mass basis) with 1.2 gm/cc bulk density, how much water volume needs to be added or removed before you start compaction for the 15 m long, 3 m high compacted dam with a bottom width of 5 m and top width of 2 m (trapezoidal section).The bulk density of the soil needs to be increased to 2 gm/cc, and it needs to be done at 15% moisture content.

Therefore, the volume of soil that needs to be added or removed = 140 - 84 = 56 m³At 10% moisture content, the soil density is 1.2 gm/cc, and it needs to be increased to 2 gm/cc by adding or removing water. The soil moisture content can be increased by adding water, and it can be reduced by removing water. In this case, water needs to be added to the soil.

The amount of water required to achieve the optimum moisture content can be calculated using the following formula: Water volume = (Final soil volume x Final soil density x Final moisture content) - (Initial soil volume x Initial soil density x Initial moisture content) = (84 x 2 x 0.15) - (140 x 1.2 x 0.10) = 4.02 m³Therefore, 4.02 m³ of water needs to be added to the soil to achieve the desired moisture content and bulk density.

The angular speed of the rod, when it lands on the horizontal surface is 1.61 rad/s.

(b) The the angular acceleration of the rod, just before it touches the horizontal surface is 1.06 rad/s² .

Angular acceleration of the rod

The angular acceleration of the rod is calculated as follows;

Apply the principle of conservation of angular momentum;

τ = Iα

where;

τ is torque

I is moment of inertial of the rod

α is the angular acceleration

τ = Fr = mg(L/2) cosθ

I = mL²/3

mg(L/2) cosθ =  mL²/3(α)

g(1/2) cosθ =  L/3(α)

(³/₂)g cosθ  = L(α)

(³/₂ L)g cosθ  = α

1.5Lg cosθ  = α

1.5(2.1) cos (70.4) = α

1.06 rad/s² = α

Angular speed of the rod

ωf² = ω₁² + 2αθ

ωf² = 0 + 2(1.06)(70.4π/180)

ωf² = 2.605

ωf = √2.605

ωf = 1.61 rad/s

Answer:

A.) Time = 17.13 seconds

B.) Distance = 31.9 m

C.) V = 11.18 m/s

D.) V = 7.1 m/s

Explanation:

The initial velocity U of the automobile is 15.65 m/s.

 At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile with initial velocity U = 0 at a constant acceleration of 1.96 m/s². Because the police is starting from rest.

For the automobile, let us use first equation of motion

V = U - at.

Acceleration a is negative since it is decelerating with a = 3.05 m/s² . And

V = 0.

Substitute U and a into the formula

0 = 15.65 - 3.05t

15.65 = 3.05t

t = 15.65/3.05

t = 5.13 seconds

But the motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s².

The total time required for the police car to overtake the automobile will be

12 + 5.13 = 17.13 seconds.

b.) Using the third equation of motion formula for the police car at V = 11.18 m/s and a = 1.96 m/s²

V^2 = U^2 + 2aS

Where S = distance travelled.

Substitute V and a into the formula

11.18^2 = 0 + 2 × 1.96 ×S

124.99 = 3.92S

S = 124.99/3.92

S = 31.88 m

c.) The speed of the police car at the time it overtakes the automobile will be in line with the speed zone which is 11.18 m/s

d.) That will be the final velocity V of the automobile car.

We will use third equation of motion to solve that.

V^2 = U^2 + 2as

V^2 = 15.65^2 - 2 × 3.05 × 31.88

V^2 = 244.9225 - 194.468

V = sqrt( 50.4545)
