Why centripetal force can not produce torque?
Torque is proportional to the distance between the center and the line of force. Centripetal force acts toward the center along the radius, so the distance between the center and the line is zero. (When your car is up on the lift, you can't make a wheel rotate by pushing on the hub.)
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?
if large force is applied keeping the minimum moment arm then it produces a very small torque or even no torque.
Is there any torque if force is zero?
NO. not at all b/c torque is directly related to force
What is An example of case when resultant force is zero but torque is not zero?

Is Work done by centripetal force is zero?
An object moves in a circle at constant speed. The work done by the centripetal force is zero because: 1. the displacement for each revolution is zero 2. the average force for each revolution is zero 3. there is no friction 4. the magnitude of the acceleration is zero 5. the centripetal force is perpendicular to the velocity

Centrifugal force is reactionary force of centripetal force?
Yes true. But they need not be got cancelled though their resultant is zero.
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.
How it is possible for a large force to produce only a small or even zero torque?
if large force is applied keeping the minimum moment arm then it produces a very small torque or even no torque.
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.
Is there any torque if force is zero?
NO. not at all b/c torque is directly related to force

Why work done by centripetal force during half rotation is zero?
work done is zero because force is toward the centre and distance is tangent to the circle so cos90 is equal to zero.[abbasia]
Give an example of a case when the resultant force is zero but resultant torque is not zero?
A couple.
