A single movable pulley
Suspend two pulleys on a cord from a horizontal support, and load them as shown. If there is no adjustable support on the expression desk, a window stick laid across the back of two chairs will serve. Join a spring balance to the end of the cord and compare the weight of the object with the force needed to lift it with the pulley system.
