🔍 Key Concepts

• Use Pascal’s Law for hydraulics: pressure in a confined fluid is transmitted equally in all directions. • Remember the basic formula Pressure = Force ÷ Area when force is given in pounds and area in square inches, giving pressure in psi. • Match the units carefully: pounds (lb) for force and square inches (in²) for area, and compare to the answer choices in psi.

💭 Think About

• From the illustration, what force is acting on the fluid, and over what piston area is that force distributed? • If you divide the given load by the piston area, what numerical value do you get, and which answer choice is closest to that? • Do any of the answer choices look unreasonable if you consider that increasing the load or decreasing the piston area increases pressure?

✅ Before You Answer

• Verify you are using Pressure (psi) = Load (lb) ÷ Piston area (in²) with no extra factors. • Confirm that you are not mixing kg with lb or cm² with in² in the actual calculation; stay in one unit system. • After computing the pressure, compare your result to each option and pick the one with the closest psi value and matching metric equivalent.
