A lifting jack is being used in the tank erection site for lifting of various heavy items. Some of the technical details of the lifting jack is as follows. pump piston diameter = 13 mm Load piston diameter = 78 mm. Calculate the force needed on the pumping piston to raise a load of 100 kN. Calculate the pressure of the oil inside the jack. What is the effect of increasing the pump piston diameter to 18 mm.
