A magnetorquer or magnetic torquer (also known as a torque rod) is a satellite system for attitude control, detumbling, and stabilization built from electromagnetic coils. The magnetorquer creates a magnetic dipole that interfaces with an ambient magnetic field, usually Earth's, so that the counter-forces produced provide useful torque.
To keep things simple, we're going to focus on structures with a circular cross section, often called rods or shafts. When a torque is applied to the structure, it will twist along the long axis of the rod, and its cross section remains circular.
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. Calculate individual torques about a common axis and sum them to find the net torque.
18 Σεπ 2019 · TRP All-Makes Torque Rods are manufactured in the USA and are designed to prevent bushing walk-out and for an extended life. TRP Torque Rod Assemblies have rubber bushings to maximize vibration absorption and extend the life of your suspension.
A small marble is attached to the end of a thin rigid rod of length \(L\), whose other end is held fixed at the origin. The rod lies in the \(x-y\) plane, and makes an angle \(\theta\) up from the \(x\)-axis, as shown in the diagram.

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. An important quantity for describing the dynamics of a rotating rigid body is torque. We see the application of torque in many ways in our world.
