The beam cross section below is idealised into booms and thin skins. The section is symmetrical about the y axis. It is a closed section but an imaginary cut has been made on the left hand side in order to find the q, distribution. A shear force of S; is applied. The shear flow is constant between the booms and the q, components are shown in the shaded blocks (with direction).

Transcribed Image Text:The beam cross section below is idealised into booms and thin skins. The section is symmetrical about the y axis. It is a closed section but an imaginary cut has been made on the
left hand side in order to find the q, distribution. A shear force of S, is applied.
The shear flow is constant between the booms and the q, components are shown in the shaded blocks (with direction). The constant component, qo is also shown.
