When a rope is pulled across a fixed cylinder, as shown in the figure below, the tension in the rope is greater on one side than the other because of friction between the rope and the cylinder. In this example, the force required to lift the 500 N weight will be greater than 500 N since the friction force resists the movement. In statics, you will learn that the relationship between the two forces is as follows: T2 = Tleue where T1 is the applied load, u is the coefficient of friction, a property of the two contacting materials, and is the contact angle in radians.
