Question

an elevator (mass 4850kg) is to be designed so that the max acceleration is 0.0680g. what are the max and min forces the motor should exert on the suporting cable?

1. why did they add 1. wouldn't it just be Fn=m(a+g), which would be 4850(0.680g+ 9.8)?

Step 1

The maximum tension on the elevator can be calculated using given steps.

Given:

Step 2

The free body diagram of elevator is given in the above figure. According to this diagram the tension and weight of th...
