Question

20 points A stelange iron loaded in comprsin. is e to increseits ridity, Althogh the wo ends are atachd by ies ends (Figure 5.27a) are to be assumed. The length is 965 mm, the cross-sectional area is 0.4 m parallel to either side is 6 mm, but the minimum radius of gyration (about a centroidal axis at 45° to the sides) is only 5 mm. What comp 2 the and the yield strength 350 MPa. The radius of gyration about centroidal axis compressive load (in kN) can be carried with a safety factor of 4? (Buckled shape shown dotted)
