The basic idea behind any hydraulic system is very simple: Force that is applied at one point is tranitted to another point using________

• A compressible fluid

• An incompressible fluid

• A cold compress

• A hot compress

It's important for a hydraulic system to contain what?

• Air bubbles

• No air bubbles

• Compressible fluid

• Compressible gas

Hydraulics is branch of science and engineering concerned with the use of liquids to perform___________

• Electrical task

• Magnetic task

• Mechanical task

• Electronic task

Hydraulics is branch of science and engineering concerned with the use of liquids to perform___________

• Electrical task

• Magnetic task

What is type of this cylinder

• Double acting cylinder

• Spring return cylinder

• Single acting cylinder

• 5/2 way double solenoid

The difference between single acting and double acting cylinders is:

• Single acting cylinders are smaller than Double acting cylinders

• Double acting cylinders have two pistons

• Work can be done in two directions in double acting cylinder unlike single acting cylinders.

Pneumatics is concerned with a system that uses:

• Oil

• Expanded air

• Compressed air

• Electricity

A 3/2 valve has

• 1.5 ports

• 3 ports and 2 directions

• 3 directions and 2 ports

• 5 ports and 2 directions

A double acting cylinder has

• has only one port

• has a return spring

• has no return spring

• has two return springs

This Schematic diagram is used to show ----------------valve

• Shuttle

• Dual

• And gate
