A loaded elevator with very worn cables has a total mass of 2200 kg, and the cables can withstand a maximum tension of 28,000 N. (a) Draw the free-body force diagram for the elevator. In terms of the forces on your diagram, what is the net force on the elevator? Apply Newton’s second law to the elevator and find the maximum upward acceleration for the elevator if the cables are not to break. (b) What would be the answer to part (a) if the elevator were on the moon, where g = 1.62 m/s2?

Solution 50P a)The free diagram for the elevator is The direction of the net force is upward We know that Newton's second law F =ma The +ve y direction to be upward since that is the direction of the acceleration. The maximum...
