What is the principle of torque?

Principles of torque and force generation: Torque is created by an energized stator coil with angle-dependent permanent magnetic flux linkage (illustrated at the top for two different rotor angles), while force is created by field strengthening and weakening (illustrated at the bottom).

What is torque defined as?

torque, also called moment of a force, in physics, the tendency of a force to rotate the body to which it is applied. Torque is measured in newton metres in SI units.

What do you mean by torque moment of force?

Torque (also known as moment, or moment of force) is the tendency of a force to cause or change the rotational motion of a body. It is a twist or turning force on an object. Torque is calculated by multiplying force and distance. It is a vector quantity, meaning it has both a direction and a magnitude.

What is torque explain it by giving two examples?

1.The rotating force (torque) used when opening a bottle cap.The rotating force when using a wrench to turn a lug nut (balance point is lug nut itself) 2. Even the spin/turn of the wheel of the car or the turn of a merry-go-round involves torque. 3.

What does torque mean in physics?

Torque is a measure of how much a force acting on an object causes that object to rotate. In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, ‘a’ being the angle between r and F.

What is torque state its applications?

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Different terminologies such as moment or moment of force are interchangeably used to describe torque.

What is a torque in physics?

How is torque related to force in kinematics?

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force.

How is the magnitude of the torque determined?

In Imperial units, you may see pound-force-feet (lb⋅ft) which might be abbreviated as pound-foot, with the “force” implied. The magnitude of torque depends on how much force is applied, the length of the lever arm that connects the axis to the point where the force is applied, and the angle between the force vector and the lever arm.

Which is the right hand rule for torque?

The Right-Hand Rule for Torque. A tricky part of working with torque is that it is calculated using a vector product. The torque is in the direction of the angular velocity which would be produced by it, so, the change in angular velocity is in the direction of the torque.

How is torque defined in the real world?

Net Torque. In the real world, you often see more than one force acting on an object to cause torque. The net torque is the sum of the individual torques. In rotational equilibrium, there is no net torque on the object. There may be individual torques, but they add up to zero and cancel each other out.
