For the beam shown below, construct the shear and bending moment diagrams for the loading listed below. Using textbook (Mott) appendix designated below, determine the lightest bridge beam shape that will carry the load. Note: do not use a safety factor. P A F X1 X2 B C Beam Table: A-7(SI) Properties of steel wide-flange shapes (W-shapes) SI units Beam Material Table: A-16 use A-36 carbon steel. Information provided below. For the problem above use these values: X1= X2= F = P = 6 m 8 m 3.2 kN/m 20 KN A-16 Properties of structural steels.
