Question: What is the principle behind the working of a hydraulic lift?

Options:

Correct Answer: Pascal\'s law

Solution:

A hydraulic lift works on Pascal\'s law, which states that pressure applied to a confined fluid is transmitted undiminished in all directions.

What is the principle behind the working of a hydraulic lift?

Step 1: Understand that a hydraulic lift is a machine used to lift heavy objects.
Step 2: Learn about fluids, which are liquids or gases that can flow.
Step 3: Know that when you apply pressure to a fluid in a closed space, that pressure spreads out evenly in all directions.
Step 4: This spreading of pressure is explained by Pascal's law.
Step 5: In a hydraulic lift, there are two cylinders filled with fluid: a small one and a large one.
Step 6: When you push down on the small cylinder, the pressure from your push is transmitted through the fluid to the larger cylinder.
Step 7: Because of Pascal's law, the larger cylinder pushes up with the same pressure, allowing it to lift heavy objects.
