A hydraulic lift is used to lift a car that weighs 1200 kg. The foot pedal is attached to a piston that has an area of 80 cm2. This is attached to a lift with a large piston with an area of 3500 cm2. What force needs to be applied to the small piston in order to lift the car? ? N How far will the smaller piston need to be pushed in order to raise the car by 2 meters
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.
