________________________________________________________________________ PROBLEM (12.35) A beam is supported and loaded as shown in Fig. P12.34. Using the workenergy method, determine the deflection at point C (or D) owing to bending and shear. SOLUTION See solution of Probs. 12.15 and 11.23: P2a2 3P 2 a Ub = (a + L) Us = ( a + L) 6 EI 5 AGL Thus, P2a2 3P 2 a 1 U= (a + L) + (a + L) = PvC 2 6 EI 5 AG a 3 or vC = 2 Pa(a + L)[ + ] 6 EI 5GAL 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.
