37239 Lecture : Torque notes
Document Summary
Torque is a measure of the force that causes an object to rotate around an axis or pivot point. It is an important concept in physics and engineering, particularly in the design and operation of machines and mechanisms. One way to determine torque is by using principles of geometry. Specifically, torque can be calculated as the product of force and the perpendicular distance from the axis of rotation to the point where the force is applied. Torque = force x perpendicular distance where torque is measured in units of newton-meters (nm), force is measured in units of newtons (n), and perpendicular distance is measured in units of meters (m). To illustrate this concept, consider the following example. Suppose a person is using a wrench to turn a bolt. The person applies a force of 50 n to the end of the wrench, which is 0. 3 meters away from the center of the bolt.
