Hydraulic brakes use Pascal's principle. The driver exerts a force of $100$ N on the brake pedal. This force is increased by the simple lever and again by the hydraulic system. Each of the identical wheel cylinders receives the same pressure and, therefore, creates the same force output F$\_\{2\}$ The circular cross$-$sectional areas of the pedal and wheel cylinders are represented by A$\_\{1\}$ and A$\_\{2\}$ respectively.

What is the pressure at the output of the pedal cylinder?

MPa

What is the output force F$\_\{2\}?$

N
