You use a pulley system to lift a fallen tree . you apply a force of 50 n and the pulley pulls on the tree with a force of 1300 n what is the mechanical advantage of the pulley ?

Mechanical Advantage = (output force) / (input force)

Mechanical Advantage = (1300 N) / (50 N)

Mechanical Advantage = 26
