Question

Four advantage of liquid pressure
Pls answer fast.....

Answer 1

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.

Answer 2

1. Ease and accuracy of control: By the use of simple levers and push buttons, the operator of a hydraulic system can easily start, stop, speed up and slow down.
2. Multiplication of force: A fluid power system (without using cumbersome gears, pulleys and levers) can multiply forces simply and efficiently from a fraction of a pound, to several hundred tons of output.
3. Constant force and torque: Only fluid power systems are capable of providing a constant torque or force regardless of speed changes.
4. Simple, safe and economical: In general, hydraulic systems use fewer moving parts in comparison with mechanical and electrical systems. Thus they become simpler and easier to maintain.
