What is torque when force applied to axis of rotation?

Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration. The direction of the torque vector depends on the direction of the force on the axis.

What will be the effect if force is applied parallel to the axis of rotation?

In this case the magnitude of the torque is just T=rF and the direction of the torque vector is parallel to the axis so Ta=T=rF and equation (1) tells us that the disk will start rotating.

Is there any effect of rotation on torque?

A torque is a force applied to a point on an object about the axis of rotation. The size of a torque depends on (1) the size of the force applied and (2) its perpendicular distance from the axis of rotation (which depends both on the direction of the force plus its physical distance from the axis of rotation).

How does the direction of an applied force affect the torque?

The magnitude of the torque depends on: Applied force F: Larger forces increase torque. Angle between the force and lever arm θ: Directing a force perpendicular to the lever arm increases the torque.

Why does a force directed through an axis of rotation not cause rotation at the axis?

Why does a force directed through an axis of rotation not cause rotation of the axis? There must be a force and lever arm for rotation to occur, which creates rotation or torque on the joint. If force is applied directly to the axis of rotation, there wont be any rotation, as the lever arm is equal to 0.

Why would a force directed through the axis of rotation not cause rotation?

As may be observed in Figure 13-2, the moment arm is the shortest distance between the force’s line of action and the axis of rotation. A force directed through an axis of rotation produces no torque, because the force’s moment arm is zero.

Which force Cannot rotate?

No Centripetal force can move a body along a circle . But it cannot produce rotation .

Why must a torque be defined about a rotational axis?

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.

How does net torque affect angular acceleration?

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.

What is torque torque?

Torque 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. torque is a force applied to a point on an object about the axis of rotation.

What causes an object to rotate with angular acceleration?

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.
