Answer:
2200 W
Explanation:
Use the given relation between current, voltage, and power to find the power requirement:
P = IV
P = (20 A)(110 V) = 2200 W
Answer:
the correct answer is option B. W
Answer:
E = 8.83 kips
Explanation:
First, we determine the stress on the rod:

where,
σ = stress = ?
F = Force Applied = 1300 lb
A = Cross-sectional Area of rod = 0.5
Therefore,

Now, we determine the strain:

Now, the modulus of elasticity (E) is given as:

<u>E = 8.83 kips</u>
A.
It would be released without a doubt so be careful!
Hope this helps :)
