Working cylinder radii ratio,    R1/ R2 = 100. Mass on bigger piston, F2 = 62.5 tonnes. Thus the ratio of area for the system, A1/A2 = 100, 00. Now applying the formula, F1/A1 = F2/A2. F1 = F2 X (A1/A2) = 62.5 X 100, 00 = 62.5 X 104 tonnes. Thus mass on the smaller piston needed to balance the system is 62.5 X 104 tonnes.

Fluids are those substances that have the property of flowing. Liquids and gases are fluids. The normal force acting per unit area on the surface of the fluid is called pressure. If A is the normal force acting on the unit area A then pressure P = F/A. The pressure impressed on a surface depends on the normal force applied and the surface area. If the area is small then the pressure will be large.
