PROBLEMS 11-1. 11- 11 11-2. 11-3. 11-4. Determine the critical load for a pinned-end col- umn made of a circular bar of SAE 1020 hot-rolled steel. The diameter of the bar is 20 mm, and its length is 800 mm. Repeat Problem 11-1 with the length of 350 mm. Repeat Problem 11-1 with the bar made of 6061-T6 aluminum instead of steel. Repeat Problem 11-1 with the column ends fixed instead of pinned. Repeat Problem 11-1 with a square steel bar with the same cross-sectional area as the circular bar. For a standard DN 25 steel pipe used as a column, determine the critical load if it is 2.05 m long. The material is similar to SAE 1020 hot-rolled steel. Compute the critical load for each of the four end conditions described in Figure 11-3. 11-5. 1 11-6. Jan
11-6 Fixed Ends 0 415KN 0 400KN O 395kN O 325kN
11-6 Fixed Pinned O 30KN O 35kN O 33kN 0 27.8kN
11-6 Pinned 0 17.7kN O 20kN 0 25kN O 15kN
11-6 Fixed Free O 5.5kN 04.01kN 0 3.01kN O 6.01kN
11-6 effective length for fixed free is O 403mm O 410mm O 400mm O 425mm
11-6 effective length for fixed pinned is 0 145mm O 145mm 0 153mm 0 160mm
