Screw Jack with Friction Calculator (Motion in the Opposite Direction of the Load)
Find the effort force while using a screw jack accounting for friction with the motion going in the opposite direction of the load.
Calculate:
effort force at end of arm
load:
lead of screw thread:
radius of screw thread:
coefficient of friction:
lever arm length:
