Introduction Concept of Stress 
1 
Equilibrium of a deformable body, average normal and shear stress, bearing stress, allowable stress, factor of safety, deformation. 
Stress and Strain  Axial Loading 
2 
Normal and shear strain, the tension test, Hooke’s law, Poisson’s ratio. 
3 
Elastic deformation of an axially loaded members, principle of superposition, statically indeterminate axially loaded member, thermal stress. 

Torsion 
4  The torsion formula, power transmission. 
5  Statically indeterminate torqueloaded members, torsion of noncircular shafts.  
Pure Bending  6  Shear and moment diagrams, the flexure formula. 
7  Bending of composite beams, stress concentrations, eccentric axial loading, unsymmetric bending.  
Shearing Stress in Beams and ThinWalled Members.  8  The shear formula, shear stresses in beams, shear flow in builtup members. 
Transformation of Stress and Strain
