Which object involving pascal principle

• 
• 
• 
• 

Hydraulic systems apply a force to a small surface area, and then the pressure is

• transmitted to another surface area which is larger.

• transmitted to another surface area of the same size.

• transmitted to another surface area which is smaller.

When a force is applied to a confined fluid, the change in pressure is transmitted

• with more force to the rest of the fluid.

• with less force to the rest of the fluid.

• equally to the parts of the fluid.

Which of the following best suit the statement below?

Pressure applied to an enclosed fluid is transmitted undiminished to every point in the fluid and to the walls of the container.

• Bernoulli’s principle

• Pascal’s principle

• Archimedes principle

• Newton’s law

In a car lift, compressed air exerts a force, F₁ on a small piston having a radius of 5.5cm. This pressure is transmitted to a second piston of radius 20cm as shown in figure above. The mass of the car is 1250kg. Acceleration due to gravity g=10ms^-1.

Calculate the pressure on the smaller piston F_1.

(Pressure exerted by fluid on large and small piston is same- Pascal's Law)

• 100kPa

• 130kPa

• 99.5kPa

• 151.2kPa

If a hydraulic system has 1000 N applied to the input piston and has an area of 81 cm², what is the pressure?

• 12.35 Pa

• 12,346 Pa

• 1235 Pa

• 123,457 Pa
