Figure Q4 shows the values of the normal and shear stresses acting on a certain stress element which is in plane stress. a) Draw Mohr's circle for this element, clearly showing the locations and values of the stresses in Figure Q4, the co-ordinates of the centre of the circle, and the radius of the circle. b) Use the Mohr's circle drawn in (a) to find the principle stresses and maximum shear stress associated with this stress element, and locate and label them on the circle. Show the principle stresses on a stress element oriented at the principle stress angle. c) Use the Mohr's circle drawn in (a) to find the stresses acting on an element rotated by 50 degrees anticlockwise, and show the stresses on a properly oriented stress element.
