The Rexroth simulators have the following component specifications: Double acting cylinders with piston diameters of 25-mm and rod diameters of 16-mm. Cylinder stroke of 40-cm for the large cylinder and 20-cm for the small cylinder(s). Pump rated output of 8 liters/minute. Maximum cylinder pressure of 105 bar (10500 kPa). Calculate the following based on the above system specifications. Refer to the formula sheet attached to this lab: a. Piston area [Ap] and rod area [AR] in units of m2. Ap = AR x De 4 = x0.025 x 0-016? 0.00020 m? b. Maximum cylinder force in extension [FE], retraction [FR] and regeneration [Fregen]: = 0.00049 m?

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.
