Figure I shows a downhill skier. A point on a ski experiences a state of plane stress, with the components Ox, Oy and Txy shown on the figure below. a) Construct Mohr's circle of the state of stress. Indicate the following on the Mohr's circle: the principal stresses and the maximum in-plane shear stress (10 points] b) Show the principal stresses on a sketch of a properly oriented stress element [15 points) c) Determine the shear stresses and normal stresses in the plane of the maximum shear stress and show these components of stress on a sketch of a properly oriented stress element (5 points] d) Determine the absolute maximum shear component of the stress (5 points] Figure 2 Oy = 4 ksi Txy = 3 ksi Oy = 0
