Figure Q1 shows an element at maximum in-plane shear stress Tmax=82 MPa and average normal stress, oavg-35 MPa. By measuring angle 0, wise from the point of maximum in-plane shear stress; = 21° clock (i) Construct and draw the Mohr Circle. Show the point of maximum in-plane shear stress, average normal stress and angle 0, = 21° (9 marks) (ii) From the Mohr Circle obtained in QI, determine the normal stresses of Oz, oy and shear stress Ty. Sketch the orientation of the stress block. (6 marks) (iii) From the Mohr Circle obtained in Q1, determine the principal stresses of , 02 and principal angle 0,. Sketch the orientation of the stress block. (6 marks) 82 MPa 35 MPa 30° Figure Q1 Figure Q1 shows an element at maximum in-plane shear stress Tmax=82 MPa and average normal stress, oavg-35 MPa.
