_______________________________________________________________________ PROBLEM (9.49) A cold-rolled beam of W 410 x 60 section (see Table B.8) supports an axial tensile load P =400 kN, which does not pass through the centroid. What is the largest eccentricity e y ? Given: ez = 0, ( σ t ) all = 120 MPa, ( σ c ) all = 80 MPa SOLUTION y B P ey P = 400 kN , x ey P z D C 407 mm A M = 400ey W410x60 At point B: P Mc σB = + B A I 400 ×103 400ey (0.2035) + 80 ×106 = 7.61× 10−3 216 × 10−6 ey = 72.8 mm 80 = 52.6 + 376.9ey , At point A: σ A = −120 = 52.6 − 376.9ey , A = 7.61× 10−3 m 2 I = 216 × 10−6 m 4 ey = 179 mm Thus, (ey ) max = 72.8 mm 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.
