In an ideal machine, work done on load on load is equal to the work done by effort.
The efficiency of a machine is the ratio of the work done on the load by the machine to the work done on the machine by the effort.
A machine has a velocity ratio of 4. It is used to raise a load of 200 N by 4 m using an effort of 20 kgf. Find the work done on the machine. Take g=10ms−2.
