A brake master cylinder piston has an area of 1cm2. The piston in the brakes has an area of 5cm2. The master cylinder is pushed with a force of 600N. Calculate the pressure on the master cylinder piston. What is the pressure on the brake piston? Calculate the force applied to the brakes. Explain why water is not used in car braking systems.
it is no longer plenty that drinks can pass stress, fairly that they are able to no longer be compressed. The grasp cylinder is crammed with fluid held in a reservoir, that reservoir is hooked as much as a cylinder with a piston it somewhat is hooked as much as the brake pedal. The grasp cylinder is hooked as much as brake cylinders on the guy wheels by utilising brake lines or tubes. the completed device is void of air and brake fluid fills all of the cylinders and lines. each guy or woman wheel cylinder has pistons besides. once you push on the brake pedal the stress from the pedal pushes the piston interior the grasp cylinder forward. The piston tries to compress the fluid, on the grounds that this won't ensue the fluid is compelled into the brake lines. Then fluid is compelled into the wheel cylinders. the upward thrust of the fluid interior the wheel cylinders forces the pistons outward. those pistons are related to the brake shoes (drum brakes) or calipers (disk brakes). The brake shoes are pressed against the drum and or disk, which creates friction and motives the motor vehicle to slow to a supply up.
Units: 1 Pa (Pascal) = 1 N/ m^2 Equations needed: (1) F = P x A (Hydrostatic Force on Plane Surfaces) First, use equation 1 to find the pressure on the master cylinder. P1 = 600 N / .01 m^2 = 60000 Pa Second, the pressure on the brake piston is equal to the pressure on the master cylinder. P2 = 60000 Pa Third, find the force on the brake piston using equation one also. F2 = 60000 Pa x .05 m^2 = 3000 N Explanation of why water is not used in car braking systems: Water is not used in braking systems because of its low boiling point. The energy transmitted from breaking will vaporize the water in the break, thus turning it into vapor or steam , which is highly compressible. Your breaks will fail shortly after this and your vehicle to be unsafe.
