Course Learning Outcomes

Understand the concepts of stress and strain at a point as well as the stress-strain relationships with reference to mechanical design.

Calculate the tensile, compressive, and shear stresses & strains in elastic bodies.

Calculate the stresses and strains associated with thin-wall spherical and cylindrical pressure vessels.

Calculate the stresses and strains in members subjected to combined loading and apply the theories of failure for static loading.

Determine and illustrate principal stresses, maximum shearing stress, and the stresses acting on a structural member.
