Cars use a hydraulic system to transmit the force from the brake pedal to the actual brakes at wheel. If this system amplifies your foot force by 10, what is the ratio of the area of the hydraulic tube at the pedal to the area of the tube at the wheel? Use Ap for area of tube at the pedal and Aw for area of the tube at the wheel.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
