Allows air to move piston in or out 3 of 31 What are Rack & Pinion Gears? Convert between linear and rotary motion 4 of 31 What is a Capacitor? Stores charge in a circuit 5 of 31 What is a Fuse? Protects a circuit by breaking contact when current flow is too high 6 of 31 What is a Machine Screw? Temporary and secure fixing of metal parts 7 of 31 What is a Single Acting Cylinder? Allows air to move piston one way 8 of 31 What is a Non-Return Valve? Allows air/water through one way only 9 of 31 What is a Flow Control Valve? Used to regulate the flow of a liquid/gas in a hydraulic/pneumatic system 10 of 31 What is a Gear Train? Controls speed, torque, and direction of motion of an output shaft 11 of 31 What is an LED? Produces light when an electric current passes through it 12 of 31 What is a Reservoir? Used to store air/ liquid in a hydraulic/ pneumatic system 13 of 31 What is a Resistor? Used to regulate the flow of current in an electronic circuit 14 of 31 What is a Split Pin? Used to secure a castellated nut onto a bolt to prevent it from becoming loose 15 of 31 What is a Filter? Used to remove impurities from a liquid/ gas in a hydraulic/ pneumatic system 16 of 31 What is an LDR? A semi conductor device whose specific resistance changes when exposed to a light source 17 of 31 What is a Potentiometer? A variable resistor that is used to control voltage levels in an electronic circuit 18 of 31 What is a Pop Rivet? Used to secure two metal panels together 19 of 31 What is a Spring? Used to provide damping and returns to shape 20 of 31 What is a Pulley? Transmits radial motion to belt motion. Is driven by a shaft 21 of 31 What is a Relay? Switches when an electrical passes through it 22 of 31 What is a Swtich? Used to break and connect the flow of current turning a circuit on/ off 23 of 31 What is a Cold Rivet? Used to join two pieces of metal together 24 of 31 What is a Chain Drive? Provides drive to shaft via a sprocket 25 of 31 What is a Transistor? Amplifies and switched electronic signals 26 of 31 What is a Nyloc/ Self-Locking Nut? A nut which when tightened onto a tread doesn't come loose due to a nylon insert 27 of 31 What is a 3-Port Valve? Controls the flow of air to a cylinder in a pneumatic circuit 28 of 31 What is a Pressure Gauge? Measures the pressure of air in a pneumatic circuit 29 of 31 What is a Circlip/ C-clip? Stops things from moving along a shaft 30 of 31 What is a Grub Screw? Fixes parts like gears and pulleys onto shafts where a bolt head could not be used 31 of 31
