Question

What pressure is transmitted to the wheel cylinder if 200N is applied on the brake pedal of master cylinder with a radius of 12cm?

Answer 1

Answer:

pressure = force/area

force = 200N

area = πr², π =3.142, r = 12 cm = 0.12 m

pressure = 200/3.142×(0.12)²

p = 200/3.142×0.24

p = 200/0.754

p = 265.25 Nm-¹ or 265.25 Pa
