________________________________________________________________________ PROBLEM (10.36) Calculate the slope at A of the beam shown in Fig. P10.31 if the beam is a W 12 x 72 steel shape (see Table B.8). Given: M = 400 kips ⋅ in., L = 15 ft, E = 30 x 106 psi SOLUTION From Table B.8, for a W12x72 section: I = 597 in.4 See solution of Prob. 10.31: M 0 L2 θA = 24 EI Substitute the given data 400 × 103 (15 × 12) 2 θA = = 30.24 × 10−3 rad 6 24(30 × 10 )(597) Excerpts from this work may be reproduced by instructors for distribution on a not-for-profit basis for testing or instructional purposes only to students enrolled in courses for which the textbook has been adopted.
