A block and tackle with a velocity of 5 is used to raise a mass of 25kg through a vertical distance of 40cm at a steady rate,if the effort is equal to 60N,determine the distance moved by effort, work done by the effort in lifting the load and the loss of energy involved in operating the machine

Answer 1

A pulley system is used to lift a load of 300N. If the effort applied is 150N, determine the
mechanical advantage of the system.
