1.7 (B). An extruded aluminium alloy section having the cross-section shown in Fig. 1.21 will be used as a cantilever as indicated and loaded with a single concentrated load at the free end. This load Facts in the plane of the cross-section but may have any orientation within the cross-section. Given that ler = 101.2 x 10-8 m' and Try = 29.2 x 10-8 m*: NA 5 mm 30mm Omm 412 mm 25mm 17 ܥܠܠܠܠܥ 25 mm 41.2 mm 10 mm 主 lomin 30 mm Fig. 1.21. (a) determine the values of the principal second moments of area and the orientation of the principal axes; (b) for such a case that the neutral axis is orientated at -45° to the X-axis, as shown, find the angle a of the line of action of F to the X-axis and hence determine the numerical constant K in the expression = KFz. which expresses the magnitude of the greatest bending stress at any distance z from the free end.
