Mr. ANIL KUMAR.G · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Pascal's Law
 **Related Topics**: Hydraulic systems, pressure transmission in fluids
 **Prerequisites**: Understanding of pressure, force, and area.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the principle behind a hydraulic lift.
  
**Method & Steps**:
 1. Understanding Pascal's Law:
  Reasoning: Pascal's Law states that pressure applied to a confined fluid is transmitted undiminished throughout the fluid.  This means that a change in pressure at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
  Formula/Rule: $P = \frac{F}{A}$, where P is pressure, F is force, and A is area.
 2. Applying Pascal's Law to a Hydraulic Lift:
  Working: In a hydraulic lift, a small force applied to a small area generates a large pressure. This pressure is transmitted through the fluid to a larger area, resulting in a larger force. This allows for lifting heavy objects with a smaller force.
  Key Point: The pressure remains constant throughout the hydraulic system, while the force and area change proportionally.
 3. Conclusion:
  Result: Hydraulic lifts operate based on Pascal's Law.
  Verification: The amplification of force in a hydraulic lift is a direct consequence of Pascal's Law.
 ## OPTION ANALYSIS
A :x: Archimedes' principle deals with buoyancy and the upward force on objects submerged in fluids.
B :x: Bernoulli's principle relates pressure and velocity in a moving fluid; it's not directly applicable to the static pressure amplification in a hydraulic lift.
 C ✓: Pascal's Law accurately describes the pressure transmission in a hydraulic lift.
D :x: Newton's law of gravitation describes the attraction between objects with mass; it's unrelated to the operation of a hydraulic lift.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing Pascal's Law with Archimedes' principle or Bernoulli's principle:  Understanding the distinct applications of each principle is crucial.
  2.Failing to recognize the pressure remains constant in a hydraulic system: The pressure is uniform throughout the fluid, but the force varies depending on the area.
 **Quick Tips**:
  1.Remember that hydraulic systems use Pascal's Law to multiply force.
  2.Visualize the pressure being transmitted equally throughout the confined fluid in a hydraulic lift.
