A simple device that runs over pulleys used to study the laws of motion & forces is known as Atwood's machine. Learn the working of Atwood machine in different cases and important points.
Frictionless case, neglecting pulley mass. Application of Newton's second law to masses suspended over a pulley: Atwood's machine. For hanging masses: m 1 = kg. m 2 = kg. the weights are. m 1 g = N. m 2 g = N. The acceleration is.
The free body diagrams of the two hanging masses of the Atwood machine. Our sign convention, depicted by the acceleration vectors is that m 1 accelerates downward and that m 2 accelerates upward, as would be the case if m 1 > m 2. An equation for the acceleration can be derived by analyzing forces.
Atwood's machine is a device invented in 1784 by the English physicist Rev. George Atwood. (See Fig. \(\PageIndex{1}\) ) The purpose of the device is to permit an accurate measurement the acceleration due to gravity \(g\).

The Atwood Machine is a pulley system consisting of two weights connected by string. We will assume no friction and that both the string and pulley are massless. If the masses of the two weights are different, the weights will accelerate uniformly by a.
Figure 1: Atwood machine with free body diagrams for m 1 and m 2. Image courtesy of HyperPhysics. Explanation: The weights of the masses attached to the string that is draped over the pulley are significantly greater than the mass of the pulley and the string.
