Question: At a curtained point in a strained material the intensities of stress on two planes at right angle to each (30 + 30) N/mm 2

At a curtained point in a strained material the intensities of stress on two planes at right angle to each (30 + 30) N/mm² and 10N/mm². They are accompanied by a shear stress of magnitude 10N/mm². Draw the moher’s circle of stress and determine the magnitude and direction of principle stress and also greatest shear.
