Quiz on Pascal's Principle

According to Pascal's principle, how is pressure transmitted in a fluid at rest in a closed container?

• It is transmitted only to the bottom of the container.

• It is transmitted without loss to every portion of the fluid and to the walls of the container.

• It is transmitted only to the top of the container.

• It is transmitted only to the sides of the container.

In a hydraulic system based on Pascal's principle, if the second piston has an area 10 times that of the first, how does the force on the second piston compare to the force on the first piston?

• The force on the second piston is 10 times greater.

• The force on the second piston is 10 times less.

• The force on the second piston is the same.

• The force on the second piston is 5 times greater.

What is the relationship between pressure, force, and area according to Pascal's principle?

• Pressure is equal to the force multiplied by the area.

• Pressure is equal to the force divided by the area.

• Pressure is equal to the area divided by the force.

• Pressure is equal to the force minus the area.
