Can there be torque when net force is zero?

Can there be torque when net force is zero?

If an object is in motion at a constant speed and constant direction, and/or is rotating at a constant rate, then that means there is no linear or angular acceleration which implies that the net force and net torque are equal to zero–which implies equilibrium.

What happens when the net force on a body is zero?

1) Translational equilibrium: If the net force acting on a body is zero, then the body is said to be in translational equilibrium. In such a case, the center of mass of the body remains either at rest or moves rectilinearly with constant velocity.

Can net force be zero but torque nonzero?

According to Newton’s third law, the sum of all the internal torques is zero. For an object to be in mechanical equilibrium, the net external force and the net external torque acting on the object have to be zero. The total torque can be nonzero, even though Ftot = 0.

Under what conditions does torque become zero?

That is, when line of action of forces passes through the axis of rotation, torque is zero.

Can the torque on a particle be zero without the force being zero explain?

(a) Can the torque on a particle be zero without the force being zero? (a) If the torque is zero then r × F = 0 Now N = r × F hence N = 0 ⇒ r or F is zero, or r and F are parallel. i.e. yes. either r = 0 (the force is acting at the origin) or r and F are parallel; and so F is acting in a direction through the origin.

When there is no torque and force then system is called?

For a body to be in equilibrium, there must be no net force acting on it. In addition, there must be no net torque acting on it. This force is called the equilibrant.

When net force on the body is zero Which of the following may be zero *?

When the net force of the body is equal to zero, it implies that the body cannot be accelerated. This follows from Newton’s second law of motion.

What is the force when acceleration is zero?

If there is zero acceleration, that means there is no net force on the object, or .

Is torque net force?

In mechanics, the net force is the vector sum of forces acting on a particle or object. Its associated torque, the net force, becomes the resultant force and has the same effect on the rotational motion of the object as all actual forces taken together. …

Why is torque considered as the rotational analogue of force?

To move an object in linear motion we need to apply a push or pull and this push or pull is known as force. Torque is the product of the magnitude of the force and perpendicular distance from the axis of rotation to the point where force is being applied. Hence, a rotational analog of force is Torque.

Does net torque equal net force?

Net torque changes the rotational velocity of an object. Net force changes the velocity of an object.
