Hydraulic machines are an integral part of our daily lives. When you go by a bus, both the steering and the brakes use a hydraulic system. Alternatively, if you use an elevator at the workplace, you are working with a hydraulic system.
You come across hydraulic machines on a daily basis . . . but do you know how they work?
It uses Pascal’s Principle, which says pressure that is applied to a fluid is transmitted unchanged throughout the whole fluid. Just an additive, the reason it works is because the pressure is the same but the area is different. This makes the total pressure multiply.
Hydraulic machines make use of the power of fluid to perform work. They are very popular because of power can be transferred through the liquid in small tubes.
Let us check out an example of how they work. Some hydraulic machines use a couple of pistons, which are devices that slide in a cylinder. Hoses filed with oil attach the pistons.
Force applied to one piston, referred to as the “Master” piston. The force moves through oil in the hose and pushes up the second “Slave” piston. The larger the “Slave” piston, the greater the force that has needed to push it up!
Hydraulic machines make our lives much easier and now you know how they work!
