What you'll be able to do
Understand the concepts of basic structural members subjected to uni-axial and bi-axial loads. Construct the shear force and bending moment diagrams along the length of beam. Compute the stresses of a member subjected to flexural and torsional loads. Determine the transverse shear stresses and deflections of beams due to bending loads. Estimate the stresses in pressure vessels and analyze the columns for buckling
