You have to figure out what mechanism you want to use to impart this force by using the torque of your electrical motor. The torque-angle relationship for an engine or machine depends on the the amount of work required. I have calculated the maximum force needed to shear the materials. This formula is always the same, meaning horsepower is always a function of torque and engine speed. A small body, of mass 82 g, is fastened to a wheel and rotates in a circular path of 456 mm diameter.
