Hydraulic lift' works on the basis of

Options

A. Stoke's law
B. Bernoulli's law
C. Pascal's law
D. Toricelli's law

Answer

To solve the question regarding how a hydraulic lift works, we will break down the explanation into clear steps.

### Step-by-Step Solution:

1. **Understanding the Hydraulic Lift**:
A hydraulic lift is a device used to lift heavy objects using the principle of hydraulics, which involves the use of liquid to transmit force.

2. **Identifying the Principle**:
The operation of a hydraulic lift is based on a fundamental principle in fluid mechanics known as Pascal's Law.

3. **Defining Pascal's Law**:
Pascal's Law states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid without any loss. This means that the pressure exerted on the fluid is transmitted equally in all directions.

4. **Application of Pascal's Law in Hydraulic Lifts**:
In a hydraulic lift, when a small force is applied to a small piston, it creates pressure in the liquid. According to Pascal's Law, this pressure is transmitted equally to all parts of the liquid, allowing a larger piston to lift a heavier load.

5. **Conclusion**:
Therefore, the hydraulic lift works on the basis of Pascal's Law, which allows for the multiplication of force through the use of incompressible fluids.

### Final Answer:
The hydraulic lift works on the basis of **Pascal's Law**.
