The column supports a load acting at the centroid and a load kN acting on the bracket at distance , from the load P 1 . The column is a W shape with m, GPa, and MPa. (a) What is the maximum compressive stress in the column? (b) If the load P 1 remains at 340 kN, what is the largest permissible value of the load P 2 in order to maintain a factor of safety of 1.8 with respect to yielding? s Y 290 E 200 L 5 310 * 52 s 250 mm P 2 110 P 1 340 kN 11Ch11.qxd 9/27/08 3:39 PM Page 888...
