A cantilevered beam with a rectangular cross section is acted upon by a 15kN force at its free end directed as shown.
a. Determine the state of stress at point A
b. Determine the equivalent state of stress on an element at point A in terms of the principal stresses. Indicate the orientation of this element.
c. Determine the equivalent state of stress on an element at point A in terms of the maximum in-plane shear stress and the associated normal stress. Indicate the orientation of this element.
