الوصف
a physics lab instrument used to demonstrate Pascal's principle.
Features
Pascal's Law: This principle states that a change in pressure at any point in an enclosed fluid is transmitted equally throughout the fluid.
How it works:
The apparatus typically consists of a U-shaped tube with pistons of different sizes. When a force is applied to one piston, the pressure created in the fluid is transmitted equally, causing the other piston to move.
Applications:
This principle is the foundation for hydraulic systems, which are used in devices like hydraulic jacks, car brakes, and hydraulic lifts.
