By Pascal's principle
\(\frac { { F }_{ 1 } }{ { A }_{ 1 } } =\frac { { F }_{ 2 } }{ { A }_{ 2 } } \)
F1 - Force of the input piston
F2 - Force of the output piston
A1 - Surface area of the input piston
A2 - Surface area of the output piston
F1 = 100N, A1 = 10 cm2, A2 = 3000 cm2, F2 =?
\(\frac { 100 }{ 10 } =\frac { { F }_{ 2 } }{ 3000 } \)
F2 = \(\frac { 100x3000 }{ 10 } \)
F2 = 30,000N
