What is Hydraulics?

 Hydraulics is a technology and applied science using engineering, chemistry, and other sciences involving liquids' mechanical properties and use. Fluid Mechanics provides the theoretical foundation for hydraulics, which focuses on applied engineering using the property of fluids. Hydraulic is used for the generation, the transmission of power by pressuring fluid, controlling, and many applications. 

About the Project?   

This project comes under "FLUID MECHANICS". 

Hydraulic Powered Track is a wonderful application for fluid mechanics, these are used in the applications of parking systems or if there is huge traffic on the bridges this system comes under consideration. In the project, the track is hydraulically regulated using syringes loaded with fluid. 

It consists of a predesigned form that is guided in a constrained way to obtain the required output. The process is governed by a law introduced by Pascal known as Pascal's Law.

Pascal's law states that:

"when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container."

The concept behind doing this project:-

The basic concept used in the project was Pascal's law. The law states that when pressure is applied at one end of a fluid constrained in a constrained volume the pressure due to that force is equally transmitted to all points of the fluid, which are acted upon by the same pressure. Using the same concept of the law it is implemented in the project. 

Principle of Hydraulic System

From the above image, it can be depicted that as the pressure is applied to the syringe the fluid gets transmitted through a tube where another syringe is connected. The motion of the syringe is used to move the track from one floor to another as shown in the figure. The desired displacement due to one syringe will move the track to a certain height to be elevated from one track to another.

Applications and Advantages of Hydraulic-powered Track:-

We require hydraulic bridges because hydraulic systems have many advantages as compared to purely mechanical and electrical systems.

• Ease and accuracy of control.

• Multiplication of forces. 

• Maintenance is comparatively less.

• Constant force and torque.

But there are also some short Disadvantages:-
