Torque is the tendency of a force to rotate the body to which it is applied.Torque is always specified with regard to the axis of rotation. It is equal to the magnitude of the component of the force lying in the plane perpendicular to the axis of rotation, multiplied by the shortest distance between the axis and the direction of the force component. Torque is the force that affects rotational motion; the greater the torque, the greater the change in this motion.
Whereas,work is the measure of energy transfer that occurs when an object is moved over a distance by an external force, some component of which is applied in the direction of displacement.
For a constant force, work W is equal to the magnitude of the force F times the displacement d of the object, or W = Fd. Work is also done by compressing a gas, by rotating a shaft, and by causing invisible motions of particles within a body by an external magnetic force. No work is accomplished by simply holding a heavy stationary object, because there is no transfer of energy and no displacement. Work done on a body is equal to the increase in energy of the body. Work is expressed in units called joules (J). One joule is equivalent to the energy transferred when a force of one newton is applied over a distance of one metre..

FranTorque is a measure of the rotational force required to turn an object, while work is the product of force and displacement in the direction of the force applied. Torque is measured in units of force multiplied by distance (e.g. Nm), while work is measured in units of force multiplied by distance (e.g. Joules).

What are the differences between positive and negative torque in mechanical systems?
Positive torque in mechanical systems causes rotation in one direction, while negative torque causes rotation in the opposite direction. Positive torque is typically associated with tightening or accelerating, while negative torque is associated with loosening or decelerating.
Does torque and work are equivalent?
No, torque and work are not equivalent. Torque is a measure of rotational force applied to an object, while work is done when a force acts on an object to move it over a distance in the direction of the force. Torque is specific to rotational motion, while work is a measure of energy transfer.
What is the work done by torque in rotating an object?
The work done by torque in rotating an object is the amount of energy transferred to the object to make it rotate. Torque is a force that causes an object to rotate around an axis, and the work done by torque is calculated by multiplying the torque applied to the object by the angle through which the object rotates.
What is about distance that make the torque and work different?
Distance in the context of torque refers to the perpendicular distance between the pivot point and the point where the force is applied. The further this distance, the greater the torque created. In contrast, in the context of work, distance refers to the distance over which a force is applied, and the work done is directly proportional to this distance. So, while distance affects both torque and work, it does so in different ways due to the different mechanisms involved.
When torque is applied does it always accomplish work?
No, torque is a twisting force that can be applied to an object without necessarily resulting in work being done. For work to be accomplished, the torque must cause the object to rotate and move a distance in the direction of the force.
