Determine the least-weight W shape simply supported beam to carry a uniformly distributed dead load of 1.1 k/ft including its self-weight and concentrated dead loads of 3.4 kips and live loads of 6 kips at the third points of a 24 ft span. Lateral supports are at the supports and at the third points. Live load deflection is limited to L/360. Use A992 steel and design by LRFD. (Be sure to check all strength limit states).
