27 Μαΐ 2024 · Design and Working Principle. The design of Atwood’s Machine is elegantly simple. It consists of two masses, often referred to as ‘m 1 ‘ and ‘m 2 ‘, connected by a light, inextensible string that runs over a frictionless pulley.
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 Basic Approach to Solving a Two-Body Problem. The solution to any two-body problem (including Atwood's Machine problems) will typically include two analyses: A System Analysis: Used to determine the acceleration. An Individual Object Analysis: Used to determine an “internal force”. Straightening the System.
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.

An Atwood's machine (two masses connected by a string that stretches over a pulley) and a modified version of the Atwood's machine (one of the masses is on a horizontal surface) can be explored. The environment allows a user to change the amount of mass, introduce friction into the horizontal surface and measure the time for the system to move ...
The machine itself consists of two masses, usually denoted by m 1 and m 2 connected by a massless string that is draped over a massless, ideal pulley. This is depicted in Figure 1. When m 1 is equal to m 2, the system is in equilibrium and neither mass experience acceleration.
