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.
