When moving an object with a mass of 500 kg using a screw with an effective diameter of 33 mm and a lead length of 10 mm lead angle 530, the required torque is obtained as follows.The ball screw requires a minimal starting torque due to its rolling motion, and does not cause a slip, which is inevitable with a sliding motion.
