Pascal’s law is applied daily in hydraulic systems, such as in vehicle brakes, where a small force on the brake pedal is transmitted to multiply stopping force at the wheels. Other applications include hydraulic lifts at auto shops, hydraulic jacks for lifting heavy objects, and hydraulic presses used in manufacturing Hydraulic Brakes When you press the … Read more
