2.2 The following data pertains to a hydraulic press: The diameter of the plunger ram are 50 mm and 0.5 m respectively. The ram is 1.75m below the plunger and the mass density of the liquid in the hydraulic press is 820 kg/m^3. The mass of the plunger and the ram are 6kg and 400 kg respectively. The plunger is forced vertically down by a lever with a mechanical advantage of 6 to 1 onto which a force of 800N is applied. The ram moves upwards when the plunger moves downwards. Determine the maximum lifting force exerted by the ram.
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.
