Problem 13P

Problem

(II) An elevator (mass 4850 kg) is to be designed so that the maximum acceleration is 0.0680g. What are the maximum and minimum forces the motor should exert on the supporting cable?

Problem 13P

Solution 13P:

Pre-calculation of minimum and maximum forces that the motor should be capable of delivering is an important part in elevator designing in terms of safety of passenger.

Step 1 of 4

Concept:

Newton’s second law: The force F acts on mass m produces an acceleration a in the object. Mathematically,

F=ma
