The foot pedal on hydraulic brake system exerts a force of 45 lbs on a piston with a diameter of 1.00 cm. The brake fluid in the brake system exerts the pressure from the foot pedal on a brake pad piston with a diameter of 2.50 cm. The force on the brake pad is (1.6pts) 402 lbs. 281 lbs. 133 lbs. 350 lbs. 150 lbs
Hydraulic mechanical advantage (2.5^2/1^2) 6.25 :1. Force on pad (45 x 6.25) 281.25lbs.
Pressure Force / Area : that's all there is to the problem. Just the definition.!!!!
