Pascal's Principle
Mediumphysics
Hydraulic lift advantage arises because?
Select the correct option:
Solution
Incorrect! Answer:
Pressure transmitted uniformly
- Pascal's Law: Pressure applied to any part of a confined incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of the container.
- Hydraulic Principle: For two pistons of areas A1 and A2:
- P=F1/A1=F2/A2.
- Force Multiplication: A small force F1 can lift a very large load F2=F1(A2/A1).
- Conservation: While force is multiplied, work/energy is conserved (the small piston must travel a much larger distance).
