Question: 1 / 400

A force of 5,000lbs is applied to a plunger with an area of 25sqin. What is the system pressure?

100psi

150psi

200psi

To determine the system pressure, you can use the formula for pressure, which is defined as the force applied per unit area. The formula is:

Pressure (P) = Force (F) / Area (A)

In this scenario, a force of 5,000 lbs is applied to a plunger with an area of 25 sq in. Plugging these values into the formula gives:

P = 5,000 lbs / 25 sq in = 200 lbs/sq in or psi

Therefore, the pressure in the system is 200 psi. This correctly represents how pressure is calculated in a hydraulic system, showing that pressure increases when a greater force is applied over the same area. Understanding this relationship is critical for elevator mechanics, as it informs the design and functioning of hydraulic systems used in elevators.
