Question

Devices like hydraulic brakes and hydraulic lifts operate based on which physical law orprinciple?

A.

Newton's law

B.

Archimedes principle

C.

Pascal's law

D.

Faraday's law

Correct option is C

The correct answer is: (c) Pascal's law

Explanation:
Devices like hydraulic brake sand hydraulic lifts operate based on Pascal's Law, which states that pressure applied at any point in a confined fluid is transmitted undiminished in all direction sthrough out the fluid. In simpler terms, if a force is applied at one point in a hydraulic system, the pressure is transmitted to other parts of the system, allowing for the multiplication of force. This principle enables machines like hydraulic lifts to lift heavy loads with relatively small amounts of force.

Information Booster:

  • Hydraulic Lifts: In hydraulic lifts, a small force applied on a small-area piston generates a much larger force on a larger-area piston, enabling the lifting of heavy objects with ease. This is essential in applications like car lifts and industrial machines.

  • Fluid Pressure Transmission: Pascal’s Law is fundamental in all hydraulic systems, as it explains how force can be multiplied and transmitted through a fluid medium, facilitating various mechanical functions.

Additional Information:
  • Archimedes' Principle: This principle relates to buoyancy, stating that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the displaced fluid.

  • Newton’s Law: Newton's laws of motion describe the relationship between forces and the motion of objects, which underpins much of classical mechanics.

  • Faraday’s Law: This law relates to electromagnetism, specifically how a changing magnetic field induces an electric current.
