The tensile strength of a material can be defined as, ‘the ability of a material to stretch without breaking or snapping’.

   
TENSILE TESTING.
A simple workshop test can be seen below. A piece of material is clamped in a vice. A fixed weight is hung from the end. The amount of deflection, is a measure of its resistance and tensile strength. A selection of materials of the same section, cut to exactly the same size, can be tested in this way.
 
 
 
 
ELASTICITY TESTING.
The elasticity of a material can be defined as, ‘the ability of a material to absorb force and flex in different directions, returning to its original position’.

A simple workshop test for elasticity can seen below. A piece of material is clamped in a vice. A fixed weight is hung from the end and the material bends / deflects. When the weight is quickly removed, the material ‘springs back’. The amount of deflection, is a measure of its elasticity. A selection of materials of the same section, cut to exactly the same measurements, can be tested in this way.
