Question

A load of 500N is raised 0.2m by a machine in which an effort of 150N moves 1m.What is a) the work done on the load b)the work done by the effort c)the efficiency

Answer 1

As you should have learned by now, work is force x distance. Use that relationship to answer (a) and (b).
For the efficiency (c), divide load work (from a) by effort work (from b). In this case (c), the answer is 2/3.

Further help on other questions you post here will not be provided by me unless you some effort is evident.
