Question

The effort required to lift a box of mass 200kg with the help of a lever 2.5m long ,if the load arm is 0.5m take g=10N/kg​

Answer 1

Answer:

To calculate the effort required to lift the load we divide the load by the number of ropes (do not count the rope that goes to the effort). The image on the right shows a four pulley system. The person lifting the 200kg load experiences a pull equal to only 50kg (200kg/4).
