What is the formula used to calculate the pressure in a hydraulic system?

The formula used to calculate the pressure in a hydraulic system is derived from the basic principle that pressure is defined as force applied per unit area. In mathematical terms, pressure is expressed as the force exerted on a surface divided by the area over which that force is applied.

Therefore, the correct formula is Pressure = Force / Area. This means that if you know the total force being exerted and the area over which that force is applied, you can easily calculate the pressure within the hydraulic system. For example, if a hydraulic piston has a force of 100 Newtons exerted on an area of 2 square meters, the pressure would be 50 Pascals (100 N / 2 m²).

The other options do not accurately represent the relationship between force, area, and pressure. They either misapply the arithmetic operations or do not reflect the proper concept of pressure in hydraulic systems.
