Two pistons push down on the fluid filling two cylinders connected by a narrow hose,as shown in the figure.The area A₁ is 1 square inch,and the area A₂ 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>2</sub> in psi is A) 0.25. B) 0.4. C) 4. D) 10. E) 40.

-The pressure on A₂ in psi is

Quizplus · Accepted Answer

Pressure is defined as force divided by area. Since the force exerted by piston 1 is 4 pounds, the pressure it exerts on the fluid in cylinder 1 is 4 pounds divided by 1 square inch, which gives a pressure of 4 psi. Because the fluid is incompressible, the pressure will be the same throughout the connected cylinder and hose system. Therefore, the pressure on the larger piston (A₂) with an area of 10 square inches is also 4 psi.
