Why torque produce by centripetal force is zero?
The torque produced by centripetal force is zero because the force is acting perpendicular to the radius of rotation. Torque is calculated as the force multiplied by the distance from the axis of rotation, and when the force and distance are perpendicular to each other, the torque becomes zero.
Can a force produce a torque when there is no lever arm?
no because to get a torque you must multiply lever arm by force. If lever is zero, then torque is zero
How it is possible for a large force to produce only a small or even zero torque?
A large force can produce a small or zero torque if the force is applied at a point where the lever arm (distance from the point of rotation to the line of action of the force) is very small or zero. Torque is calculated as force multiplied by lever arm, so a small lever arm can result in a small or zero torque even with a large force.
Why torque is zero when force is applied to point that passes through pivot point?
Torque is defined as the product of the distance from the pivot point, times a force, times an angle function. If any of the three factors is zero, the product is zero. In this case, the distance from the pivot point.
What is An example of case when resultant force is zero but torque is not zero?
A common example is a see-saw where two forces balance each other out and create a zero resultant force, but the torques produced by the forces are not equal because they act at different distances from the pivot point. This results in a non-zero net torque causing rotation.
How do you Convert Torque Nm to Force N?
Torque T=Nmsin x, thus Force N=T/msin x. If sin x is zero Torque is zero and Force is zero.

Give an example of a case when the resultant force is zero but resultant torque is not zero?
A couple.
A planet revole around the sun under the affect of gravitation exerted by the sun why the torque on the planet due to gravitation force is zero?
Because torque is (magnitude of the force) x (distance between the point where the force is applied and the center of rotation). Gravitational force is always directed toward the center of rotation, so the second factor is zero, and the torque is therefore zero.
How will an object move if it is acted on by a positive net torque and force of zero?
A torque will make it rotate - or change its rotation.
If the net force on an object is 0 is the net torque 0?
Not necessarily. The net force being 0 means the object is in translational equilibrium, but the net torque can still be non-zero if there are unbalanced forces causing rotation.
When A force of 5 newton is acting parallel to the moment arm of 10 cm . so what is torque?
In order for a force to produce a torque, either all of it, or a part of it (component) must act perpendicular to the moment arm. If, as in your case, all of the force is parallel to the moment arm then the force can not produce a torque. So the answer is; the torque is zero.
What is An example of case when resultant force is zero but torque is not zero?
A common example is a see-saw where two forces balance each other out and create a zero resultant force, but the torques produced by the forces are not equal because they act at different distances from the pivot point. This results in a non-zero net torque causing rotation.
If the net force on an object is zero is the net torque zero?
Yes. If an object is at rest or in a linear motion state at constant speed, the net force applied onto the object is zero.
