Question

A fully loaded elevator at maximum capacity weighs 2400 lbs. The counterweight weighs 1000 lbs. The elevator always starts from rest at its maximum acceleration of g/4 whether it is going up or down. (a) What force does the wall of the elevator shaft exert on the motor if the elevator starts from rest and goes up

Answer 1

Answer:

2250lb

Explanation:

Using

1000-T=(1000/g)(g/4)

So

T = 750lb

Then

750+F-2400= 2400/9

So F= 2250lb
