Activity #5: Calculating Power At the beginning of the gear activity section, we discussed the mathematical formula for torque ( t = rF ). In this activity, we will introduce additional variables for distance of a circle and revolutions per second. A tangential force at a crank radius of r will move through a distance of 2 x r each time the shaft makes one complete revolution. This movement creates a certain amount of work as described as:
Materials: Calculate the power supplied by a motor running at 3400 rpm while delivering a torque of 800 foot lbs.
