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.

Torque. A torque is an influence which tends to change the rotational motion of an object. One way to quantify a torque is. Torque = Force applied x lever arm . The lever arm is defined as the perpendicular distance from the axis of rotation to the line of action of the force.
a) The following diagram shows a convenient choice of using either position vector, \(\vec r\) or the moment arm \(r_{\perp}\) to solve for the torque due to each force. Force \(\vec F_1\) is parallel to the position vector \(\vec r_1\).
Torque is the rotational counterpart of force. Suppose a body rotates about an axis and a force \(F\) is applied some distance \(r\) from the axis (Fig. \(\PageIndex{1}\)). The distance from the rotation axis to the point at which the force is applied is called the moment arm.
18 paź 2024 · Because it is a product of some distance and a physical entity like force, torque is also called moment of force. r is called the length of the moment arm or lever arm. Also, since the rotating object describes a circle, r is the radius. Notice that the longer the lever arm, the higher the torque.
26 maj 2024 · Torque is the rotational equivalent of linear force. It is determined by two key factors: the magnitude of the force applied and the distance from the point of rotation, commonly referred to as the lever arm. The basic formula for torque (\( \tau \)) is given by: \[ \tau = r \times F \]
A practical way to calculate the magnitude of the torque is to first determine the lever arm and then multiply it times the applied force. The lever arm is the perpendicular distance from the axis of rotation to the line of action of the force.
