740 CHAPTER 9 Deflections of Beams Problem 9.5-17 The compound beam ABC shown in the figure has a guided support at A and a fixed support at C . The beam consists of two members joined by a pin connection (i.e., moment release) at B . Find the deflection d under the load P . Solution 9.5-17 Table G-1, Case 4 D EFLECTION UNDER THE LOAD P Table G-2, Case 6 d B ± P (2 b ) 3 3 EI d ± 6 Pb 3 ; d ± P ( b ) 6 c 3( b )(8 b ) ² 3 b 2 ² b 2 d + P (2 b ) 3 3 d ± P ( b ) 6 c 3( b b ) ² b ) 2 ² ( b ) 2 d + d B Problem 9.5-18 A compound beam ABCDE (see figure) consists of two parts ( ABC and CDE ) connected by a hinge (i.e., moment release) at C . The elastic support at B has stiffness k ± EI/b 3 Determine the deflection d E at the free end E due to the load P acting at that point. Solution 9.5-18
