It'd be best if I start with example.
Screwdriver helps us by having a handle with a large radius that provides a mechanical advantage in turning a blade with a smaller radius. So whatever force exerted on screwdriver's handle by hand, same force is exerted on screw. But torque on a handle is different from torque on a blade?
Next question
If you pull a body with certain force it will start accelerating and exert equal but oposite force on you.
Is there something similar with torques? If I make an object rotate will I experience same kind of torque caused by that object?
This question also relates to internal torques, since the sum of internal torques in a system is zero. If me and an object I made rotate comprise a system, then all internal torques should sum to zero. Will there be torque on my body with same magnitude? I don't get it!
thanx
