Question

In hydraulic brakes, the max force can be applied is 250N. A vehicle of 2500kg to
be lifted by this force. What should be the ratio of radius of output piston to
radius of input piston? (g=10 unit)​

Answer 1

Answer:

Pressure on the piston P=

A

F

Force F=m×a

=3000×9.8

=29400 N

Area of cross section A=425×10

−4

sqm

Therefore the pressure P=

425×10

−4

3000×9.8

=6.92×10

5

Pa.
