WebAt the end you can reduce the force slightly and the screw will come to rest. The total work done to move the mass up is independent of how much the mass was accelerated as long as it it at rest at the beginning and end of the exercise - and thus the average force will be exactly as calculated. WebPut a 2 foot diameter handwheel on it and your hand moves 75 inches for every revolution (circumference). That means you get a force multiplication of 600:1 (the ratio of 75 and 1/8th inches). Therefore, 17 lbs of force on a 1 foot handle ( 2 foot handwheel) attached to a screw with a thread pitch of 8 results in 5 tons of force. incarnation\u0027s bu
