Final answer:
The front brakes provide a percentage of the total braking force in a hydraulic brake system. This is determined using Pascal's principle and the formula F2 = F1 * (A2/A1). By calculating the force output at each of the wheel cylinders, we can determine the percentage of braking force provided by the front brakes.
Step-by-step explanation:
The front brakes provide a certain percentage of the total braking force in a hydraulic brake system. This percentage can be determined using Pascal's principle, which states that the pressure in a fluid is transmitted equally in all directions. In this case, the force exerted by the driver on the brake pedal is increased by the lever and hydraulic system.
The force output at each of the wheel cylinders can be calculated using the formula:
F2 = F1 * (A2/A1)
where F1 is the force exerted by the driver on the brake pedal, A1 is the cross-sectional area of the pedal cylinder, and A2 is the cross-sectional area of each wheel cylinder. By rearranging this formula, we can calculate the percentage of braking force provided by the front brakes:
Percentage = (F2/F1) * 100
So by plugging in the appropriate values for F1, A1, A2, we can determine the percentage of braking force provided by the front brakes.
