________________________________________________________________________ PROBLEM (10.12) Calculate the deflection at the center of the beam shown in Fig. P10.10 if the beam is a solid rod of diameter d. Given: d = 2 in., P = 80 lb, L = 3 ft, E = 10 x 106 psi. SOLUTION See solution of Prob.10.10: P (24 Lx 2 − 42 L2 x + 19 L3 ) v1 = 48 EI For x=L/2: 1 PL3 1 80(3 ×12)3 = 39.6 ×10−3 in. vC = = 12 EI 12 10 ×106 (π × 24 64) 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.
