Considering only pure bending, determine the minimum section modulus for the component and loads shown. Assume ?? of 36,000 psi and a factor of safety of 1.67. (Hint: the part does not have to exceed the allowable stress) Do not forget to draw and calculate the diagram of shear force and bending moment The distances in the beam are in feet.

A shaft stepping from 2" to 3" has a fillet radius of 0.25". Compute the maximum bending stress, in psi, if it is under a bending moment of 6149 lb-in.
Compute the initial deflection of the beam at midspan under service loads with the following specifications: f'c = 4000 psi, 36-inch height, depth of rebar assumed to be 3 inches less than the height, 16-inch width, 4 #9 bars (tension), Grade 60 rebar, 30' clear spans, service loads of: DL = 0.25k/ft, LL = 1.2k/ft. The DL does NOT include self-weight of the beam or of the precast concrete deck planks that have a weight of 60 PSF. The beam picks up a tributary width of 12 feet. Also, note that this beam is continuous and is the middle beam of 5 equal spans. Check the initial deflections against the ACI deflection requirements. Then calculate the long-term deflections and check those against the ACI requirements. For both situations, assume that finish materials will be attached to the beam.
