Main Question or Discussion Point
I have a rather simple question but not having had physics since college, I am unable to find the solution to a problem. Given a shaft with a 500 lb wheel mounted to it how would I calculate the torque on the shaft? The wheel is 2 feet in diameter and 2 feet wide. The shaft is 2 inches in diameter and if I were to change the size of the wheel, say to double the weight and or diameter, is there an easy way to calculate the new torque value?
