Mechanical Properties of Solids
Stress, Strain, and Hooke's Law
Defines normal stress, longitudinal strain, and Hooke's law of proportionality within the elastic limit.
Young's Modulus and Elongation of a Wire
Relates longitudinal stress to longitudinal strain and gives the elongation of a uniform wire under tension.
Shear Modulus of Rigidity
Gives the ratio of tangential shearing stress to shear strain angle in a solid.
Bulk Modulus and Compressibility
Relates excess hydraulic pressure to fractional volume compression, with compressibility as its reciprocal.
Poisson's Ratio
Gives the ratio of fractional lateral contraction to fractional longitudinal extension in a stretched body.
Elastic Potential Energy and Energy Density
Gives the work stored as elastic potential energy in a deformed wire and the energy per unit volume.
