answer only 9.14 please, big thanks!
Extracted text: 9.13 Figure (a) shows the cross section of a column that uses a structural shape known as W8 x 67 (wide-flange beam, nominally 8 in. deep, weighing 67 Ib/ft). The American Institute of Steel Construction Structural Steel Handbook lists the following cross-sectional properties: A= 19.7 in.?, ī,=272 in.“, and Îy = 88.6 in. Determine the dimensions of the rectangle in Fig. (b) that has the same I; and īy as a W8 x 67 section. 0.933 in. Web. 9 in. -0575 in. -Flange -8.287 in.- (a) (b) Fig. P9.13-P9.15 9.14 Compute the dimensions of the rectangle shown in Fig. (b) that has the same k, and ky as the W8 x 67 section in Fig. (a). (See Prob. 9.13 for properties of W8 x 67.) Answer: b = 7.35 in. h = 12.87 in.
