This apparatus can model how the use of several pulleys increases one's mechanical advantage. A pulley is a variation of the wheel and axle, in which a rope or cord is stretched over a wheel to make it rotate as the rope is pulled.

Students can use this both qualitatively and quantitatively and its design lends itself easily to scientific enquiry based activities.
