Question

Hydraulic press is based on the ________ law.

Answer 1

1. According to Pascal's law, pressure at a point in a static fluid is transmitted equally in all directions.
2. On applying a small pressure on the plunger of a hydraulic press, the fluid used in the press is pushed beneath.
3. Due to the uniform pressure transmitted to the plunger of the hydraulic press, it rises.
4. The pressure between the plunger and the ram causes the body to crush when placed between them.

Hence, the hydraulic press is based on Pascal's law.
