Question

Question 11 3 pts The steel (E = 29 x 103ksi) angle below has its smallest radius of gyration about the a-a axis, ra=0.628 in and its area is 2.505 in2. Calculate the largest axial stress that can be applied through its centroid C, if it is to be used as fixed-fixed connected 10-ft-long column without causing it to buckle. Give your answer in ksi to 2 decimal places. Notegy = 50 ksi. a
