On a stress element, the following stresses are acting: σ x = 5 ksi (Compression) σ y = 10 ksi (Tension) τ xy = 0 Ksi Using the equations given below: (1) Calculate the principal stresses and the plane and draw principal plane and the stresses acting on it. (2) Calculate maximum shear stress and maximum shear plane and then draw the shear plane and the stresses acting on it. (3) Calculate the average stress.
