Unformatted text preview: 09Ch09.qxd 9/27/08 1:30 PM Page 707 9 Deflections of Beams Differential Equations of the Deflection Curve y The beams described in the problems for Section 9.2 have constant flexural rigidity EI. Problem 9.2-1 The deflection curve for a simple beam AB (see figure) is B A given by the following equation: q0 x (7L4 360LEI x 10L2x2 + 3x4) L Describe the load acting on the beam. Probs. 9.2-1 and 9.2-2 Solution 9.2-1 Simple beam q0 x (7L4 360LEI 10L2x2 + 3x4) Take four consecutive derivatives and obtain: –– q0 x LEI From Eq. (9-12c): q EI –– q0x L ; The load is a downward triangular load of maximum ; intensity q0. 707 ...
