A hydraulic automobile lift is designed to lift cars with a maximum mass of 300 kg. the area of cross-section of the piston carrying the load is 425cm^(3) . What maximum pressure would smaller piston have to bear?

When a pressure measuring device is immersed in a liquid, a restoring force of 2 N is exerted by the spring. If the area of cross-section of the pistion is 10 cm^(2) , what pressure does the fluid exert on the piston?

The figure shows a schematic layout of hydraulic jack. The load to be raised weighs 20,000N. The area of cross section of the two pistons are A_(1)=50cm^(2) and A_(2)=10cm^(2) . The force (F) is applied at theend of a ligh lever bar as shown in the figure. Lenghts a and b are 4cm and 36cm respectively. Find the force (F) required to raise the load slowly.

2 moles of a diatomic gas are enclosed in a cylinder piston arrangment. The area of cross section and mass of the piston are 1 cm^(2) and 1 kg respectively. A heater is supplying heat to the gas very slowly. Find heat supplied (in joule) by the heater is the piston moves through a distance of 10 cm. .

Consider a vertical tube open at both ends. The tube consistss of two parts, each of different cross sections and each part having a piston which can move smoothly in respective tubes. The two piston which can move smoothly in respective tube wire. The piston are joined together by an inextensible wire. The combined mass of the two piston is 5 kg and area of cross section of the upper piston is 10 cm^(2) greater than that of the lower piston. Amount of gas enclosed by the pistons is 1 mol . When the gas is heated slowly, pistons move by 50 cm . Find the rise in the temperature of the gas in the form X//R K , where R is universal gas constant. Use g = 10 m//s^(2) and outside pressure = 10^(5) N//m^(2)) .

A lift is tied with thick iron wire and its mass is 1000kg . If the maximum acceleration of the lift is 1.2ms^(2) and the maximum stress of the wire is 1.4xx10^(8) Nm^(2) what should be the minimum diameter of the wire?

An object of weight 500 kg_(wt) is lifted by using a hydraulic press. The radii of the cross sections of the pump piston and press piston are 10 cm and 20 cm, respectively. Calculate the effort required to lift the object. Calculate the displacement of the load if the effort is moved through a distance of 20 cm.
