An S 6 ( 12.5 steel cantilever beam AB is supported by a steel tie rod at B has shown. The tie rod is just taut when a roller support is added at C at a distances S to the left of B, then the distributed load q is applied to beam segment AC. Assume E = 30 ( 106 psi and neglect the self weight of the beam and tie rod. See Table E-2(a) in Appendix E for the properties of the S-Shape beam.
(a) What value of uniform load q will, if exceeded, result in buckling of the tie rod if L1 = 6 ft, S = 2 ft, H = 3 ft, d = 0.25 in.?
(b) What minimum beam moment of inertia Ib is required to prevent Bucking of the tie rod if q = 200 lb/ft, L1 = 6 ft, H = 3 ft, d = 0.25 in., S = 2 ft?
(c) For what distances S will the tie rod be just on the verge of bucking if q = 200 lb/ft, L1 = 6 ft, H = 3 ft, d = 0.25 in.?
