How to Calculate Torque on a Shaft | Sciencing

Apr 24, 2017· Torque, a measure of "twist" on a shaft, is as basic as pressure and stress in engineering mechanics. It differs from a bending moment because the vector sum of forces for torque is zero. The equation is simple, but if you are trying to calculate torque experimentally, you will need some measuring devices to ...

How to calculate the Torque required for bending wire/rod ...

M is the torque you need to apply to bend the rod. In your case, your the distance to generate the moment will vary so you need to adjust the force [ M = force * distance] as required. The only hard part is that you may need to test this, because steel grades are often higher than labeled. For example if i want to buy 36ksi steel, its 36 ksi min.
