Class Objectives:



Strength of Materials covers the relationship between stress and strain in deformable solids.
Analysis is applied to circular shafts, beams, columns and pressure vessels. Covers combined
stresses, statically indeterminate systems and pr
operties of structural materials.

Working on the
assumption of mechanical parts and structures are in static equilibrium will teach the coursings

various methods for determining the stresses, strains and deflections produced in various
mechanical systems

by applied loading.
