An element on the top surface of a fuel tanker is in biaxial stress and is subjected to stresses x = -48 MPa and ay = 19 MPa, as shown in the figure. %x1 = %y1 = Using Mohr's circle, do the following. (Consider only the in-plane stresses the stresses in the x-y-plane). (a) Determine the stresses (in MPa) acting on an element oriented at a counterclockwise angle = 20.5° from the x-axis. (Use the sign convention for stresses acting on inclined sections.) MPa MPa MPa = 19 MPa σ, 48 MPa (b) Determine the magnitude of maximum shear stress, associated normal stress, and angle of orientation of the plane of maximum shear stress. (Enter your stresses in MPa and your angle in degrees counterclockwise from the +x-axis. For the normal stress, use the sign convention for stresses acting on inclined sections.)
