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.
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.
Atwood's Machine is a device created by the Reverend George Atwood in 1784 to help demonstrate the mysteries of acceleration and force. In an ideal Atwood's Machine, two unequal masses are attached to a flexible, massless string which passes over a frictionless, massless pulley (see diagrams below).
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 purpose of this activity is to study the relationship between net force, mass, and acceleration as stated by Newton’s 2nd Law, using an Atwood’s Machine apparatus, built with a PASCO Super Pulley. The Super Pulley has very low friction and small mass.
When two objects of unequal mass are hung vertically over a frictionless pulley of negligible mass as in Figure 5.14a, the arrangement is called an Atwood machine. The device is sometimes used in the laboratory to determine the value of g.
