The data are the same as in the previous example. Suppose now, however, that the bottom surfaces of the piston and plunger are at different levels, such that h = 1.10 m in figure (b). The car lift uses hydraulic oil that has a density of 8.00 x 102 kg/m³. What is the magnitude F, of the input force that is now needed to produce an output force having a magnitude of F, = 20500 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.
(next question)
Based on the problem answered (as shown in the photo)
The data are the same as in the
previous example. Suppose now,
however, that the bottom surfaces of
the piston and plunger are at different
levels, such that h = 1.10 m in figure
(b). The car lift uses hydraulic oil that
has a density of 8.00 x 102 kg/m3.
What is the magnitude F1 of the input
force that is now needed to produce
an output force having a magnitude
of F2 = 20500 N?
