What does torque cause in a mechanical system?

Torque is a measure of the rotational force applied to an object, and its primary effect in a mechanical system is to induce rotation. When torque is applied to an object, it can create a turning or twisting motion around an axis, leading to the rotation of that object.

For instance, when using a wrench to tighten a bolt, the torque you apply results in the bolt rotating into place. This rotational effect is fundamental to understanding how mechanical systems operate, particularly in machines and engines where moving parts rely on rotation to function effectively.

While movement of load and change in direction can result from torque under certain circumstances, the direct and primary effect of torque itself is rotation. It is also important to note that torque does not increase the weight of an object; rather, it acts as a force that can cause an object to move in a rotational manner.
