A simple machine with an efficiency of 75% lift of a load of 5000N.When a force of 500N is applied to it,Calculate the velocity ratio of the machine.

Answer 1

well, the real load is 500*4/3, so force ratio is 5000/500 * 3/4=7.5
velocity ratio then is 1/7.5

If I understand what you asked.

Answer 2

A simple machine has an efficiency of 0.75 and VR of 10 . determine the MA and the load that can be moved if an effort of 100N is applied

Answer 3

A simple machine has an efficiency of 0.75 and VR of 10.determine the MA and the load that can be moved if an effort of 100N is applied
