Text Solution
Verified by ExpertsThe correct answer is:
A
Hydraulic brakes operate on the principle of Pascal's law.
Step 1: Understand Pascal's law which states that when pressure is applied to a confined fluid, it is transmitted undiminished in all directions.
Step 2: In hydraulic brakes, when the brake pedal is pressed, force is applied to a small piston, which generates pressure in the hydraulic fluid.
Step 3: This pressure travels through the hydraulic fluid and acts on a larger piston at the brake disc, allowing a much larger force to be applied to stop the vehicle.
Step 4: Since the operation of hydraulic brakes relies fundamentally on the transmission of pressure through the fluid as described by Pascal's law, the correct answer is A.
