Acran uses an average force of 5200n to lift a steel beam 25m. how much work does the crane do on the steal beam. or explain how to do this anyone. and youu
Answers: 1
is the angle between the direction of the force and the direction of motion
, 
and 
(because the force is parallel to the direction of motion), so the work done by the crane is
