Two pistons push down on the fluid filling two cylinders connected by a narrow hose, as shown in the figure. The area A ₁ is 1 square inch, and the area A ₂ is 10 square inches. A force of 4 pounds is exerted downward on piston 1, as shown.

Two pistons push down on the fluid filling two cylinders connected by a narrow hose, as shown in the figure. The area A <sub>1</sub> is 1 square inch, and the area A <sub>2</sub> is 10 square inches. A force of 4 pounds is exerted downward on piston 1, as shown. The pressure on A <sub>1</sub> is 4 psi.

The pressure on A ₁ is 4 psi.

Quizplus · Accepted Answer

Pressure equals force divided by area. The force exerted on piston 1 is 4 pounds, and the area of A ₁ is 1 square inch. Therefore, the pressure exerted on A ₁ is 4 pounds per square inch (psi).
