(a) Explain the meaning of critical load, Per
[Terangkan maksud beban kritikal, Pa]
Figure 1
[Rajah 1]
(b) Consider the beam member ABD, supported by member BC shown in Figure 1. The A-36
steel beams ABD is subjected to the load P = 50 kN and Q = 35 kN. Due to forked ends
on the member, consider the support at B and C to act as pinned for x-x axis buckling and
fixed support for y-y axis buckling. Calculate the factor of safety with respect to buckling
about each axes. Given E = 200GPa, Kx-xaxis = 1.0, Ky-y axis = 0.5.
