A 5m long steel struts connected by simply supported at the ends, and is made of a steel tube 80mm in diameter with a 40mm bore. The strut is loaded in compression by a force of 35kN, which is applied parallel to the longitudinal axis. There is an initial curvature to be observed for this strut (E = 210GN/m2, Yield stress = 300MN/m2)
- Determine the critical buckling load of the initial curvature.
- Find the additional central deflection that is caused due to this load.

A 49 in long simply supported hollow circular steel tube has a 1.68 in OD and 0.392 in wall thickness. The cross-section is shown below. Use an allowable bending stress of 1.022 kpsi for steel and find the maximum safe uniformly distributed load that the beam can carry, if the loading is in the direction. Maximum safe uniformly distributed load- lbf/in.

A steel I-section beam, simply supported at its two ends, is
subjected to a uniformly distributed load q (vertically downward)
over its central segment having a length of 2 m as shown in the
figure. It also shows the type of restraints (F/P/L) against
lateral torsional buckling of the beam at its four sections. The
section at the left end of the beam has only the lateral rotational
restraint. The load is causing bending of the beam about x-x (major...
