The beam has a length of 9 ft and is subjected to point load P = 3.7 kips at mid-span. Calculate the state of stress at point C located 4 in. below the top of the beam and 4.5 ft to the right of support A. Neglect the weight of the beam. (Enter the normal and shear
stresses in ksi. For the normal stresses, use the deformation sign convention. For the shear stress, use the sign convention for shear stresses. Consider only the in-plane stresses. Assume that the +x-axis is to the right along the length of the beam and the +y-axis
