Explain the mechanical property of stiffness as it relates to plastics.
What will be an ideal response?
Stiffness is measured by the modulus of elasticity (E). The greater the modulus of elasticity, the stiffer the material. Overall, plastics are not as stiff as steel, aluminum alloys, and concrete, so they deflect more under load.
