An elevator (mass 4850 kg) is to be designed so that the maximum acceleration is .0600 g. What are the maximum and minimum forces the motor should exert on the supporting cable?
For the maximum (assuming elevator goes up):
Is the tension force the same as the motor's exerting force (which has opposite direction)?
F_t - mg = T - 4850 kg*9.8 m/s^2 = T- 47530 N
T - 47530 N = 4850 kg*0.0588 m/s^2
T - 47530 N = 2851.8 N
T = 50,381.8 N = F_motor ???
How do I get the minimum force?
Gracias for your time, patience, and input.
