A screw jack has a square thread 50 mm mean diameter and 10 mm pitch. The load on the jack revolves with the screw. The coefficient of friction between screw and nut is 0.05. find the
tangential force required at the end of 300 mm long lever to lift a load of 6000 N. also calculate, VR, MA and efficiency.
Ans: P = 57.01 N, VR = 188.496, MA = 105.245, Efficiency = 0.5583
