Young Modulus, Stress and Strain, and Hookes Law

?
Young Modulus
Stiffness of material. Young Modulus = Stress/Strain. In GPa or Nm^-2
1 of 5
Stress
Stress = Force applied/Cross sectional Area. In Nm^-2 or GPa
2 of 5
Strain
Strain = Extension/Original Length. No units.
3 of 5
Hookes Law
F = Ke. K= Stiffness (spring constant). F= Force. e= Extension. Extension is proportional to force applied. Hookes Law is true up to the elastic limit of a material.
4 of 5
Density
Density = Mass/Volume
