An axially loaded 10’ long 2”x 6” S4S Douglas Fir stud is pinned at both ends. E= 1.4 x 106 psi Allowable compressive stress parallel to the grain = 825 psi For the strong axis: What load will cause buckling? If the weak axis were braced every 30” what is the critical buckling load about the weak axis? Neglecting buckling, what is the maximum load that can be applied to the stud before it will be crushed?
