Stress is a force acting on a rock per unit area. ... Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation). Rocks onlystrain when placed under stress. A brief description about the relationship between the two is elaborated in this lecture. Feel free to download & learn.

True stress (σ') and true strain (ε') are used for accurate definition of plastic behaviour of ductile materials by considering the actual (instantaneous) dimensions.A brief description about the same is elaborated in this lecture. Feel free to download & learn.

Elastic Constants - Stress produces strain. But how much strain is produced depends upon the solid itself. The solid is then characterized by an elastic modulus that relates strain to stress.

Based upon lecture 2 & 3 i.e stress-strain relationship & elastic constants.

Mohr's circle, named after Christian Otto Mohr, is a two-dimensional graphical representation of the transformation law for the Cauchy stress tensor.A brief description about the same is elaborated in this lecture. Feel free to download & learn.     

Normal stress is a result of load applied perpendicular to a member. Shear stress however results when a load is applied parallel to an area. Looking again at figure one, it can be seen that both bending and shear stresses will develop. Like in bending stress, shear stress will vary across the cross sectional area.A brief description about the same is elaborated in this lecture. Feel free to download & learn.

The 2nd moment of area, also known as moment of inertia of plane area, area moment of inertia, or second area moment, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.A brief description about the same is elaborated in this lecture. Feel free to download & learn.         

A beam is a structural element that primarily resists loads applied laterally to the beam's axis. Its mode of deflection is primarily by bending.A brief description about the same is elaborated in this lecture. Feel free to download & learn.
