Question

Q8. What does the figure indicate? State the principle on which the given system works.
​

Answer 1

Answer:

This figure indicate about hydraulic pressure.

It works on the principle of Pascal's law.

Explanation:

Let the force applied in first case be 100 newton and the area be 10 metre square. Then the pressure would be 10 pascals (Pressure = Force/Area).

Now here the pressure is 10 pascals and when we increase the area say 100 metre square. Then the force would be 1000 newton (Pressure = Force/Area).

So in the above example, just by applying 100 newton force we changed into 1000 newton force.

Hope, It is clear now. If you still didn't get that, let me know.

Answer 2

Answer:

The figure shows that a car is placed on a platform. The platform is lifting the car up. This figure shows that the hydraulic pressure is act on the platform. It
