A screw jack is used to lift a load of 30 kN. The screw of the screw jack is square threaded with two threads of 1.2 cm. If the coefficient of friction between the nut and screw is 0.09 and the outer diameter of the screw is 6 cm, find the force required at the end of the handle of length 60 cm to lift that load.

A 60 Kg crate is resting on top of a 45 Kg crate as shown in figure below. The top crate is attached to a wall by a cord, and a rope attached to the bottom crate passes around two fixed pegs. The coefficient of friction between the two crates is 0.4; between the crate and the floor is 0.5; and between the rope and the pegs is 0.3. Determine the minimum force Pmin needed to cause move the bottom crate. 60 kg 45 kg
