Q.3 A steel column (E = 30 x10 3 ksi) that is fixed at the base and free at the top is constructed of a W 8 x 35 wide-flange member (see figure). The column is 9.0 ft long. The force P acting at the top of the column has an eccentricity e =1.25 in. The geometric properties of section are; A = 10.3 in2, depth = 8.12 in, Imax = 127 in4, Ileast = 42.6 in4. a) If P = 40 k, what is the maximum compressive stress in the column? b) If the yield stress is 36 ksi and the required factor of safety with respect to yielding is 2.1, what is the allowable load Pallow?

Question
Q.3 A steel column (E = 30 x10 3 ksi) that is fixed at the base and free at the top is constructed of a W 8 x 35 wide-flange member (see figure). The column is 9.0 ft long. The force P acting at the top of the column has an eccentricity e =1.25 in. The geometric properties of section are; A = 10.3 in2, depth = 8.12 in, Imax = 127 in4, Ileast = 42.6 in4.
a) If P = 40 k, what is the maximum compressive stress in the column?
b) If the yield stress is 36 ksi and the required factor of safety with respect to yielding is 2.1, what is the allowable load Pallow?
