ClVE207, Fall 2008, Assignment #9 (Due Nov. 18, Tuesday 12pm, Box 2 in Room MD475) 10.21 Column AB carries a centric load P of magnitude 15 kips. Cables Be and BD are taut and prevent motion of point B in the xz plane. Using Euler's formula and a factor of safety of 2.2, and neglecting the tension in the cables, determine the maximum allowable length L. Use E = 29 X 10 6 psi .. x Fig. P10.21 \ 02{' *Prob. 10.3·12. A beam AB that supports a unifonnly distributed: . J-. ,; load of intensity w (force per unit length) is simply supported at both ends, and it rests on a pipe column at. its center C. Neglecting the weight of the beam AB, derive a formula for the value of the distributed load, w.... that would cause elastic buckling of the support column CD. Assume that the column is fixed to its base. at D and pinned to the beam at C. Express your answer in terms of the following material and geometric parameters: the modulus of elasticity, E (same for the beam A1J and the column CD); length of the beam, a, and the length of the column, L; the mo- ment of inertia of the beam.
