In this section we look at the motion of two particles attached by a light, inextensible string passing over a smooth pulley. There are several types of problem that you can get.

• Two particles hanging vertically below a pulley (introduction)
• Example 1

In some questions you are expected to find the force acting on a pulley. In the next tutorial you are shown several scenarios that you may come across.

• Force acting on a pulley from the string.
