= The tee shape shown is used as a short post to support a load of P = 4200 lb. The cross-section includes a left-side flange (1) with dimensions bfx hf, and a stem (2) of dimensions twx(d-tp). Assume L = 24 in., bf = 11.5 in., tp = 2.0 in., tw = 2.5 in. and d = 10.5 in. The load Pis applied at a distance a = 4.5 in. from the surface of the flange. Determine the normal stresses at points Hand K, which are located on section A-A. d Р (1) bi X (2) K A K H A H .X Cross section Calculate the cross-sectional area A1 of the left side flange (1), and the cross-sectional area A2 of the stem (2). Answers: A1 = i in.2, A2 = i in.2
Part 2 X Incorrect Here, the centroid of each area is the midpoint of the area along the direction of the x axis, and these centroids are measured with respect to the left side of the flange (1). Determine the location of the x direction centroid X1 of the left side flange (1) and the x direction centroid x2 of the stem (2), each with respect to the left side of the flange (1). Answers: X1 - i 5.914 in., X2= i in. e Textbook and Media Save for Later Attempts: 1 of 5 used Submit Answer
