pascal's principle

Question

Hydraulic lift advantage arises because?

RankGuru · Accepted Answer

1. **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.
2. **Hydraulic Principle**: For two pistons of areas $A_1$ and $A_2$:
   - $P = F_1/A_1 = F_2/A_2$.
3. **Force Multiplication**: A small force $F_1$ can lift a very large load $F_2 = F_1 (A_2 / A_1)$.
4. **Conservation**: While force is multiplied, work/energy is conserved (the small piston must travel a much larger distance).
