How is torque related to rotation?

How is torque related to rotation?

Torque is the rotational equivalence of force. So, a net torque will cause an object to rotate with an angular acceleration. Because all rotational motions have an axis of rotation, a torque must be defined about a rotational axis. A torque is a force applied to a point on an object about the axis of rotation.

Does torque depend on axis?

Torque is a vector quantity. The direction of the torque vector depends on the direction of the force on the axis. Someone pushing on a closed door is applying a static torque to the door because the door is not rotating about its hinges, despite the force applied.

What does direction of torque mean?

Torque is a vector. Part of the torque calculation is the determination of direction. The direction is perpendicular to both the radius from the axis and to the force. It is done by the right hand rule direction along the axis of rotation. If the rotation is anticlockwise then torque produced is upwards and vice versa.

What is torque motion?

Torque is a measure of how much a force acting on an object causes that object to rotate. The object rotates about an axis, which we will call the pivot point, and will label ‘O’. Torque is defined as Γ=r×F=rFsin(θ).

What is the torque due to the centripetal force about the axis of rotation?

The torque due to centripetal force about its axis of rotation is zero.

What is torque describe the magnitude and direction of torque?

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.

What is torque What role does torque play in the rotational motion of machine?

Torque is the rotational equivalent of force. Specifically, it is a force exerted at a distance from an object’s axis of rotation. In the same way that a force applied to an object will cause it to move linearly, a torque applied to an object will cause it to rotate around a pivot point.
