Components

Question 1

Define Gears

Answer 1

Gears are toothed wheels on shafts that transmit speed, torque, or force. The teeth on the gears interconnect.

Question 2

Define Pulleys

Answer 2

Pulleys are wheels on a shaft with taut cables around. They are designed to support movement. Pulleys can transmit lifting power, apply a force or transmit power.

Question 3

Define Bearings

Answer 3

A bearing is a component that permits rotational or linear motion. Bearings can also improve efficiency by reducing friction.

Question 4

Define Universal Joints

Answer 4

A universal joint is a component that transmits rotational motion at any required angle.

Question 5

Define a Ratchet & Pawl

Answer 5

A ratchet is designed to allow rotational motion in one direction only.

Question 6

Define a Spring

Answer 6

A spring is an elastic component that stores mechanical energy.

Question 7

Define Mechanical Fixings

Answer 7

A Mechanical Fixing is a metal used to secure two objects together, eg. Bracket

Question 8

Define Rivets

Answer 8

A rivet is a metal peg with a head on one end. Normal rivets go through the hole then hit with a hammer.

Question 9

Define Piston

Answer 9

A piston transmits reciprocating motion.

Question 10

Define crankshaft

Answer 10

A crankshaft converts linear motion into reciprocating, and vice versa.

Question 11

Define Lever

Answer 11

A lever is a rigid bar positioned on a fulcrum. A lever can make it easier to move a load.

Question 12

Define a Seal

Answer 12

A seal is any device and/or substance that joins two things together and prevents anything passing between them.

Question 13

Define Gusset Plate

Answer 13

Gusset plates are thick sheets of steel that are used to connect beams and girders to columns, or to connect truss members.

Question 14

Define Solenoid

Answer 14

A solenoid is an electromagnetic that converts electricity into linear motion. The electromagnet moves an armature towards it in a straight line.

Question 15

Define Sensor

Answer 15

A sensor detects conditions in an environment and relays this information through the circuit, so the suitable reaction can be produced.

Question 16

Define Switch

Answer 16

A device that connects and breaks an electronic circuit: turns an electric current on and off.

Question 17

Define Semi-conductor

Answer 17

A semi-conductor is a substance that can conduct electricity under some conditions, but not others. They are useful for controlling electrical current.

Question 18

Define Resistor

Answer 18

A resistor is a device that limits current in a circuit.

Question 19

Define Capacitor

Answer 19

A capacitor is a component that stores electrical charge.

Question 20

Define Motor

Answer 20

Motor converts electricity into rotary motion.

Question 21

Define Relay

Answer 21

A relay is when a small circuit is used to turn on a more powerful circuit; using an electromagnet

Question 22

Define Transformer

Answer 22

A transformer is a device that can increase, or decrease, the voltage in an alternating current circuit.

Question 23

Define LED

Answer 23

An LED allows electricity to pass through it in one direction. When it does, the diode glows.

Question 24

Define Audible Devices

Answer 24

Audible devices are components that convert noise into electricity or electricity into noise.

Question 25

Define Single Acting Piston Cylinder

Answer 25

A gas or liquid forces this piston. The piston moves and applies linear motion. The piston has a spring so it moves into the position it was before the force was applied.

Question 26

Define Double Acting Piston Cylinder

Answer 26

A gas or liquid forces this piston. The piston moves and applies linear motion. The fluid can go in either side, meaning the piston can move either way.

Question 27

Define Linear Actuator

Answer 27

A linear actuator converts energy (from air, electricity or gas) into linear motion.

Question 28

Define Valve

Answer 28

A valve is a device used for controlling the passage of fluid through a pipe or duct by opening, closing or partially blocking a pipe.

Question 29

Define Check Valve

Answer 29

A one-way valve is a component designed to allow fluids to flow in one direction only. It is normally an automated system that opens/closes according to the fluid’s velocity.

Question 30

Define Pump

Answer 30

A pump is used to move liquids and compress gases by using suction or pressure.

Question 31

Define One-Way Valve

Answer 31

A one-way valve is designed to allow fluids to flow in one direction only.

Question 32

Define Restrictor

Answer 32

A restrictor limits the power of an engine. The restrictor limits the engines top speed, and increases the safety of the engine.

Question 33

Define Quick Couplers

Answer 33

Quick couplers are components that allow tools to be attached onto a machine quickly.

Question 34

Define Reservoir

Answer 34

In a pneumatic system there are fluid reservoirs. These store fluid to be used later in other pneumatic components. The reservoir releases the fluid when it is needed in the system.

Question 35

Define Turbine

Answer 35

A turbine is a component used for producing continuous power where a wheel or rotor is made to revolve by a fast-moving flow of fluid.

Question 36

Define Fluid Flywheel

Answer 36

Fluid flywheels are pneumatic components that transmit rotary power without the use of mechanical input. Instead, motion is transmitted through the fluid in the coupling.
