0 Question 9 I In order to move a carriage (a total load P) slowly from A to B, the simple beam AB of span length L-20 ft was used by a UNC Charlotte student engineer. If the maximum bending moment is 40 kip-ft and the allowable bending stress is 40 ksi, the minimum required section modulus is in³.
