An introduction to torque, a force that causes rotation. Understand how torque is calculated as the product of force and distance, and how it differs from work. Learn about the direction of torque and its units.
Sep 12, 2022 · Learning Objectives. Describe how the magnitude of a torque depends on the magnitude of the lever arm and the angle the force vector makes with the lever arm. Determine the sign (positive or negative) of a torque using the right-hand rule.
Mar 1, 2024 · torque, in physics, the tendency of a force to rotate the body to which it is applied. The torque, specified with regard to the axis of rotation, is equal to the magnitude of the component of the force vector lying in the plane perpendicular to the axis, multiplied by the shortest distance between the axis and the direction of the force component.
Apr 6, 2023 · Torque represents the force that causes an object to rotate about an axis. Just as force causes an object to accelerate in a straight line, torque makes the object rotate about an axis with angular acceleration. Torque is a vector quantity whose direction depends on the force.
Describe how the magnitude of a torque depends on the magnitude of the lever arm and the angle the force vector makes with the lever arm; Determine the sign (positive or negative) of a torque using the right-hand rule; Calculate individual torques about a common axis and sum them to find the net torque
Nov 25, 2023 · Torque is the measure of how much a force acting on an object causes that object to rotate, creating a tendency for the object to rotate about an axis, fulcrum, or pivot. Torque is most commonly classified as "twist", rotational force, or angular force to an object and applying it to a system changes the angular momentum of the system. The ...
Torque is a vector since angular acceleration is a vector, and rotational inertia is a scalar. Let us examine which variables torque depends on by thinking about its units: τ = Iα = [kg ⋅ m2][rad s2] = [kg ⋅m2 s2] = [N ⋅ m] (7.5.2) (7.5.2) τ = I α = [ k g ⋅ m 2] [ rad s 2] = [ k g ⋅ m 2 s 2] = [ N ⋅ m]
