This test should be performed on all cord sets, receptacles that aren't part of a building or structure's permanent wiring, and

cord-and-plug connected equipment required to be grounded. The point of this test is to make sure that the equipment grounding conductor is electrically continuous.

Why is the face of the claw on a claw hammer usually a smooth curve? Why isn't it straight or some other shape?
GarryVolchara [31]

Answer:

The face of the claw on the claw hammer is usually a smooth curve so as to improve the ease with which nails are removed when removing nails because as the nail held between the V shaped split claw is being pulled out from the wood, it slides more and more towards cheek, reducing the distance of the nail from the cheek which is the fulcrum, thereby increasing the mechanical advantage because the location of the hand on the grip remains unchanged

For a bronze alloy, the stress at which plastic deformation begins is 275 MPa, and the modulus of elasticity is 115 GPa. (a) Wha
Anton [14]

Answer:

89375 N

Explanation:

Rearrange the formula for normal stress for F:

\sigma=\frac{F}{A}

F=\sigma*A

Convert given values to base units:

275 MPa = 275*10^{6} Pa

325 mm^{2} = 0.000325 m^{2}

Substituting in given values:

F = (275*10^{6})*(0.000325)=89375 N

Estimate the rotor inertia assuming that the rotor is a cylinder of radius 8.98 mm, and length 25 mm, with a material of 100% co
Softa [21]

Answer:

The moment of inertia of the rotor is approximately 1.105\times 10^{-6} kilogram-square meters.

The rotor inertia may differ from these assumption due to differences in the shape of cross section.

Explanation:

We assume that rotor can be represented as a solid cylinder of radius r, length l, made of cooper (\rho = 8960\,\frac{kg}{m^{3}}) and whose axis of rotation passes through its center of mass and is parallel to its cross section. By definition of Moment of Inertia and Theorem of Parallel Axes, the moment of inertia of the rotot is:

I = \frac{1}{4}\cdot \rho \cdot \left(\frac{\pi}{4} \right) \cdot R^{3}\cdot (3\cdot R^{2}+L^{2})

I = \frac{\pi}{16}\cdot \rho \cdot R^{3}\cdot (3\cdot R^{2}+L^{2}) (Eq. 1)

Where:

\rho - Density of copper, measured in kilograms per cubic meter.

R - Radius of the rotor, measured in meters.

L - Length of the rotor, measured in meters.

I - Moment of inertia, measured in kilogram-square meters.

If we know that \rho = 8960\,\frac{kg}{m^{3}}, L = 25\times 10^{-3}\,m and R = 8.98\times 10^{-3}\,m, the estimated moment of inertia of the rotor is:

I = \frac{\pi}{16}\cdot \left(8960\,\frac{kg}{m^{3}} \right)\cdot (8.98\times 10^{-3}\,m)^{3}\cdot [3\cdot (8.98\times 10^{-3}\,m)^{2}+(25\times 10^{-3}\,m)^{2}]

I \approx 1.105\times 10^{-6}\,kg\cdot m^{2}

The moment of inertia of the rotor is approximately 1.105\times 10^{-6} kilogram-square meters.

From D'Alembert's Formula we know that net force of rigid bodies experimenting rotation equals the product of moment of inertia and angular acceleration. In this case, the purpose is minimizing moment of inertia and it is done by modifying the shape of the cross section so that rotor could be aerodynamically more efficient.

The specifications of an electronic device are 24 /- 0.4 Amps. When the device exceeds specifications the average quality cost i
Misha Larkins [42]

Answer:

The average loss for this device is $10.90

Explanation:

Given data

Specification = 24 +/- 0.4 Amps

average quality cost = $32.00

average value y = 23.9

standard deviation s = 0.211 Amps

32 = k(24.4 - 24)²

32 = k(0.4)² = k(0.16)

k = 32/0.16 = 200

To evaluate average loss, use

L = k{s² + (y - T)²}

T = 24A

L = 200{0.211² + (23.9 - 24)²}

L = $10.90

The average loss for this device is $10.90
