This video shows a comprehensive workout on an example of Mohr’s circle representing that how much rotation required for an element to reach at principle stresses conditions. Very first, the video gives an overview on the schematic diagram of a rectangular block section that experiences normal & shear stresses of certain values. Subsequently asks to draw the Mohr’s circle in order to calculate the principle stresses, maximum shear stress & the rotation of the planes experiencing the principle stresses and maximum shear stress.

Moving next, the video determines the coordinates of Mohr’s circle with radius as well as finds out the angle of rotation using the formula derived earlier & successively uses all the obtained values to plot the Mohr’s circle. Later, the video does geometric analysis using the principle of Mohr’s circle & combined stresses & thereafter evaluates the points on the Mohr’s circle that experiences maximum shear stresses and principle stresses. Hopefully, good understanding of this example will clear the concept of Mohr’s circle mastering which is very important for the study of structural mechanics.

This course builds on the concept of force and moment equilibrium learnt from first year engineering mechanic and physics courses and focuses on the internal actions and deformations experienced by simple structural members under loading. Concepts learnt in the course such as load transfer through axial, shear, bending and torsion as well as stress and strain relationships are the foundation for further study in any structural engineering related courses.
