. Design a beam for a 30-ft simple span to support the working uniform loads of wo 1.25 k/ft (includes beam self-weight) and wi-1.75 k/ft. The maximum permissible total load deflection under working loads is 1/360 of the span. Use 50 ksi steel and consider moment, shear and deflection. The beam is to be braced laterally at its ends and the mid-span only. (25-POINTS)
