A girder of I-section has a web 60 cm by 1.25 cm and flanges 30 cm by 2.5 cm. The girder is subjected at a bending moment of 300 kNm and a shearing force of 1000 kN at a particular section. Calculate how much of the shearing force is carried by the web, and how much of the bending moment by the flanges. (Cambridge)
