Let's see how Pascal's law can be used to amplify a force. Suppose the hydraulic lift shown in (Figure 1) has a small cylindrical piston with radius 5.0 cm and a larger piston with radius 20 cm. The mass of a car placed on the larger piston's platform is 1000 kg. Engineers are designing a hydraulic lift that can be used to repair trucks with a mass of 6800 kg . What ratio of piston areas would you suggest for the design if the maximum available external force is to be 3000 N ?
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.
