Components Flashcards
Define Gears
Gears are toothed wheels on shafts that transmit speed, torque, or force. The teeth on the gears interconnect.
Define Pulleys
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.
Define Bearings
A bearing is a component that permits rotational or linear motion. Bearings can also improve efficiency by reducing friction.
Define Universal Joints
A universal joint is a component that transmits rotational motion at any required angle.
Define a Ratchet & Pawl
A ratchet is designed to allow rotational motion in one direction only.
Define a Spring
A spring is an elastic component that stores mechanical energy.
Define Mechanical Fixings
A Mechanical Fixing is a metal used to secure two objects together, eg. Bracket
Define Rivets
A rivet is a metal peg with a head on one end. Normal rivets go through the hole then hit with a hammer.
Define Piston
A piston transmits reciprocating motion.
Define crankshaft
A crankshaft converts linear motion into reciprocating, and vice versa.
Define Lever
A lever is a rigid bar positioned on a fulcrum. A lever can make it easier to move a load.
Define a Seal
A seal is any device and/or substance that joins two things together and prevents anything passing between them.
Define Gusset Plate
Gusset plates are thick sheets of steel that are used to connect beams and girders to columns, or to connect truss members.
Define Solenoid
A solenoid is an electromagnetic that converts electricity into linear motion. The electromagnet moves an armature towards it in a straight line.
Define Sensor
A sensor detects conditions in an environment and relays this information through the circuit, so the suitable reaction can be produced.
Define Switch
A device that connects and breaks an electronic circuit: turns an electric current on and off.
Define Semi-conductor
A semi-conductor is a substance that can conduct electricity under some conditions, but not others. They are useful for controlling electrical current.
Define Resistor
A resistor is a device that limits current in a circuit.
Define Capacitor
A capacitor is a component that stores electrical charge.
Define Motor
Motor converts electricity into rotary motion.
Define Relay
A relay is when a small circuit is used to turn on a more powerful circuit; using an electromagnet
Define Transformer
A transformer is a device that can increase, or decrease, the voltage in an alternating current circuit.
Define LED
An LED allows electricity to pass through it in one direction. When it does, the diode glows.
Define Audible Devices
Audible devices are components that convert noise into electricity or electricity into noise.
