Course Description

Simple and combined stress, torsion, flexure and deflection of beams, continuous and restrained
beams, combined axial and bending loads, columns.

Mechanics of materials, also called strength of materials, is a subject which deals with the behavior of solid
objects subject to stresses and strains. The study of Mechanics of materials often refers to various methods of
calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods
employed to predict the response of a structure under loading and its susceptibility to various failure modes takes
into account the properties of the materials such as its yield strength, ultimate strength, Young's Modulus, and
Poisson's ratio; in addition the mechanical element's macroscopic properties (geometric properties), such as it
length, width, thickness, boundary constraints and abrupt changes in geometry such as holes are considered.

Course Objectives

By the end of the semester, students should be able to:

1. Explain basic concepts of stress, strain and their relations based on linear elasticity
2. Calculate stresses and deformation of a bar due to an axial loading under uniform and non-uniform
conditions
3. Calculate stresses and deformation of a torsional bar
4. Sketch shear-moment diagrams of a beam and find the maximum moment/shear and their locations
5. Calculate normal and shear stresses on any cross-section of a beam
6. Apply Mohr’s circle to calculate principal stresses and angles in plane stress cases.
7. Calculate stresses on a structure under combined loadings
8. Calculate deflections of a beam under combined loads by using methods of moment-area and
superposition
9. Recognize stability and buckling phenomena for a slender member under an axial compressive force.
