The hydraulic lift (the figure below) has a small piston with the surface A₁ = 0.040 m² and a large piston with the surface A2 = 6.0 m². F₁ = 21 N. F₁ Ayı Submit A₁ Submit "What force will the large piston provide if the small piston in a hydraulic lift is moved down as shown in the figure? (Express your answer to two significant figures.) N A₂ Ayı F = ? 2) If the small piston is depressed a distance of Ay₁, by how much will the large piston rise? (Express your answer to two significant figures.) Ay2 J How much work is done in slowly pushing down the small piston if Ay₁ = 0.26 m? (Express your answer to two significant figures.)
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.
