What happens when pressure is applied to an enclosed fluid?

It moves in one direction It decreases It is transmitted equally in all directions It turns into heat

What component in a hydraulic system stores energy in the form of fluid under pressure?

Pump Valve Accumulator Cylinder

In a hydraulic press, increasing the area of the output piston will...

Decrease the pressure Increase the output force Stop fluid flow Reduce efficiency

Which device converts hydraulic energy into mechanical motion?

Hydraulic pump Hydraulic cylinder Accumulator Filter

What is the purpose of a hydraulic pump?

Why is hydraulic fluid considered incompressible?

It evaporates easily It conducts electricity It cannot be squeezed into a smaller volume It cools rapidly

What controls the direction of fluid flow in a hydraulic system?

Pump Cylinder Valve Pipe

What happens if air gets into a hydraulic system?

It improves lubrication The system becomes less efficient Pressure increases It stops working completely

What advantage do hydraulics have over mechanical systems?

They use less fluid They can transmit large forces through small components They work faster than electricity They never need maintenance
