Engineering Jc 24/25

Strength

the ability to maintain shape under the application of force

brittleness

Breaks easily when impacted

hardness

difficult to scratch or indent

Elasticity

can be deformed a lot and still return to its original state

Ductility

will stretch a lot under a pulling force

malleability

will flatten easily under a squashing force

Toughness

both strong and not brittle, difficult to break, it absorbs energy of impacts by deforming but still wont break

Transparency

see through - opposite is opaque

weight

how heavy an object is

Switch

Switches a circuit ON/OFF

LED (Light Emitting Diode)

Allows current in one direction only and gives off light

Resistor

Slows down the flow of current, protecting delicate components

Variable Resistor

Used in speed/volume control and dimmer switches

Lamp

Gives off light

Capacitor

Stores electric charge

Light Dependant Resistor

Resistance drops with increasing light; used in street lights

Motor

Provides Power/Drive; used in models, printers, etc.

Voltmeter

Measures Voltage

Ammeter

Measures Current
