What is the meaning when torque is not zero but body still not moving?

If the net torque is not zero, there will be angular acceleration. It implies the angular velocity will be continuously changing. Conversely, if angular velocity is not changing, that is , if angular velocity is constant, angular acceleration is zero and there is no torque.

What happens when the net torque on an object is not zero?

Because there is no net torque acting on an object in equilibrium, an object at rest will stay at rest, and an object in constant angular motion will stay in angular motion. Because the net torque is equal to zero, the torques in Example 1 are balanced and acting in equilibrium.

When the resultant of all the torques acting on the body is equal to zero then body is in?

equilibrium
equilibrium: The state of a body at rest or in uniform motion, the resultant of all forces on which is zero.

What does it mean if net torque is zero?

Rotational equilibrium
2) Rotational equilibrium: If the net torque acting on a body is zero, then the body is said to be in rotational equilibrium. In such a case, the angular velocity of the body remains constant.

What is resultant torque?

Resultant torque is the sum of individual torques. Resultant torque is the sum of individual torques. τ R. = – 80 N m.

When a torque acting on a system is zero What is conserved?

When the total external torque acting on the system is zero, then the total angular momentum of the system is conserved.

When the sum of the torques acting on an object is zero the total angular momentum remains constant?

Just as linear momentum is conserved when there is no net external forces, angular momentum is constant or conserved when the net torque is zero.

What happens when the net torque is not equal to zero?

The torques are no longer in equilibrium. The torque equation remains the same, but the net torque is not equal to zero. The magnitude of the net torque is given by: where the “| |” symbols indicate the magnitude of the quantity included between the ends.

Are two torques with the same magnitude but different directions equal torques?

Two torques with the same magnitude but different directions are not equal torques. In fact, where T net is the net torque acting on the pivot. Because the net torque is equal to zero, the torques in Example 1 are balanced and acting in equilibrium. There is no net torque acting on the pivot in Example 1.

What is the torque if sin(∅) is 0?

If any of these is zero, the force is zero. And, of course, if there are many torques and they cancel each other out, the total torque is also zero. *Note that (2) has to be on the same point: in a driving wheel, the forces cancel each other out, but it still spins. So when ∅ is 0° or 180° , sin (∅)=0,so torque N will be 0.

Why is the resultant torque of a car tyre zero?

The resultant horizontal force on any of its tyres is zero because the car is not accelerating or decelerating along the ground. Similarly, the resultant vertical force is zero because the tyre is not moving up or down. So the resultant force is zero but the resultant torque is not.
