The state of stress at a point is shown on the element. a. Determine the Center (C) and Radius (R) of the Mohr's circle. b. Determine the principal stresses (sigma_1 and sigma_2) and angle of principal plane (theta_P). Show the state of stresses on the principal plane, i.e., rotated element. c. Determine the maximum shear and average normal stresses (tau_max and sigma_avg) and angle of maximum shear stress plane (theta_s). Show the state of stresses on the rotated element.
