5. Lift is often explained in relationship to the principle which is depicted in the following diagram. What is that principle?

Lift is often explained with the Pascal's law.

Explanation:

Pascal's Law States that, "pressure is transmitted undiminished in an enclosed static fluid".

According to this law, pressure can be transmitted to all the parts of fluid containing container if we apply force on any point of the fluid. This principal helps in hydraulic press.

In hydraulic press, there are two cylindrical shape container that contains fluid. If we apply the pressure on one cylinder, it can produce a froce in multiple amount of pressure applied. This can be used to lift a large amount of load by applying very small pressure.

This principle is used in lift for lifting the large amount of load by applying very small force.
