Answer:
Force will be equal to 0.08522 horsepower
Explanation:
We given weight of elevator = 5000 lb
Height of the elevator = 30 ft
Time t = 320 sec
We have to calculate the power in horsepower
For let first find power in lb-ft/sec
So power in lb-ft/sec [tex]=\frac{5000lb\times 30ft}{320sec}=46.875lb-ft/sec[/tex]
Now we know that 1 horsepower = 550 lb-ft/sec
So 46.785 lb-ft/sec = [tex]\frac{46.875}{550}=0.08522horsepower[/tex]
