a brief description about the history of hydraulics

THE HYDRAULICS

Hydraulics is a branch of science that deals primarily with practical applications of liquid in motion. This science has played a crucial role in the development of modern day society, especially in the area of transportation.

EARLY HISTORY

While some historians may argue for the presence of crude hydraulic inventions earlier in history, the documented history of hydraulics began in 1785 when two men began working hydraulic inventions. The first William Armstrong noticed the energy wasted by the water wheel and set out to improve it. His contemporary, Joseph Bramah, obtained a patent for a hydraulic press a few years later.

GREATER DEMAND

The science of hydraulics remained relatively undeveloped until after the American Great Depression. As industries and consumers demanded stronger, more powerful vehicles, an employee of Muncie Power Products named Hamer Shafer began testing the effectiveness of hydraulics in vehicle engines.

HYDRAULICS TODAY

As of 2010, hydraulics plays an important role today in the function of automobiles, dams, elevators, airplanes, bicycles, trains and machinery. As this science is being fine-tuned, it has developed an increasingly important role in the development of computers and other devices.

ADVANTAGES

Hydraulic systems allow users to accurately wield large amounts of power with little input force. They also provide constant force, according to the National Fluid Power Association. In addition, hydraulic systems are safe in chemical plants and mines because they do not cause sparks.

DISADVANTAGES

Hydraulic systems contain highly pressurized fluid. This can cause burns, bruises or the accidental injection of fluid into the body, according to Colorado State University. Hydraulic systems must be periodically checked for leaks and lubricated, and filters must be changed regularly.
