What you'll learn

Find internal forces with the method of sections and compute normal, average shear and bearing stresses in members and connections.
Read a stress–strain diagram and use Hooke's law, Poisson's ratio and the shear modulus to relate stress and strain.
Calculate deformations, thermal stresses and forces in statically indeterminate axially loaded members.
Analyze shear stress and angle of twist in solid and hollow circular shafts, including power transmission.
Draw shear force and bending moment diagrams using equilibrium and the load–shear–moment relationships.
Compute bending stresses in beams with the flexure formula and select sections by section modulus.
Compute shear stresses in beams with the shear formula and check webs and built-up sections.
Combine axial, bending, torsional and shear stresses, including eccentric loads, at critical points.
Transform stresses to find principal stresses and maximum shear stress, by equations and with Mohr's circle.
Analyze thin-walled cylindrical and spherical pressure vessels and interpret strain gauge readings.
Find beam slopes and deflections by integration, superposition and energy methods, and solve indeterminate beams.
Predict buckling loads of columns with Euler's formula and effective lengths, and recognize when inelastic buckling governs.
