Material strength
Material strength
Ability to handle forces without breaking or changing shape
Three types of forces on materials
Three types of forces on materials
Tension (pulling), compression (squeezing), torsion (twisting)
Tensile strength
Tensile strength
Greatest stress material can bear while stretched or pulled
Compressive strength
Compressive strength
Ability to resist forces that try to make material smaller
Torsional strength
Torsional strength
Ability to resist twisting forces
Tensile strength test process
Tensile strength test process
Pull material sample until it breaks, check maximum stress
