Question 1:
State Pascal’s principle.

Answer:
Pascal’s principle states that the transmission of pressure exerted on a fluid (liquid or gas) in an enclosed system is uniform throughout the fluid and in all directions.


Question 2:
State the basic principle of the hydraulic system.

Answer:
The basic principle in a hydraulic system is the transmission of pressure in all directions based on Pascal’s principle.


Question 3:
Give three examples of the application of Pascal’s principle in daily life.

Answer:
Hydraulic jack system, hydraulic brake system, dental chair


Question 4:
