Consider the pulley system shown in . The system consists of six pulleys, three fixed pulleys (A, B and C) and three moveable pulleys (D, E and F), and a single mass . The pulley arrangement is designed to increase the input force ( ) in order to lift the mass (M).
The of the system is defined as the ratio of the output force (the force acting on the mass) to the input force (the force applied to the cable).
Which of the following correctly represents the of this system?
Assume the system is in equilibrium, and that the pulleys and cables are massless and frictionless.
