Year 10 Manufacturing (Resistant Materials)
Lesson 5 Week 5 (Clock Project)
Definitions of properties of Materials.
Hardness The resistance a materials has to cutting and surface indentations. Toughness This describes the amount of energy a material can absorb without breaking. This is the opposite to brittleness. We measure a material's ability to absorb shock. Tensile Strength The maximum force a material can withstand in tension(pulling) compression(squashing) , torque(twisting) and shearing(sideways pressure). Malleability The amount of hammering, pressing and shaping a material can take without breaking. Ductility The length that a material can be stretched without breaking. Elasticity The length that a material can be stretched and return to its original length when released. Heat and Electrical Conductivity The measure of how well a material can conduct heat or electricity. Heaviness The denseness of materials. A dense material will be heavy in relation to its size. Strength The measure of how a material withstands a heavy load without breaking.
