A symmetric open section is shown below. It has been fully idealised and the section data is provided. W W 60.0mm h 95.0mm h 150.0mm h 2 1 3 h B2 B3 220.0mm2 B=B4 75.0mm The section is subjected to a shear force, acting at the shear centre, with a horizontal component of 1.7kN and vertical component of 6.4kN. Assume a usual coordinate system, horizontal x and vertical y. The reference coordinate system will have an origin at the mid-point of the vertical web (panel 23).
