Your engineering firm is asked to specify the maximum load for the elevators in a new building. each elevator has mass 500 kg when empty and maximum acceleration 2.25 m/s^2. the elevator cables can withstand a maximum tension of 19.6 kn before breaking. for safety, you need to ensure that the tension never exceeds two-thirds of that value. what do you specify for the maximum load? how many 75.0-\rm kg people is that?
