Problem 10.4-3 A propped cantilever beam of length 2L with support at B is loaded by a uniformly distributed load with intensity q. Use the method of superposition to solve for all reactions. Also draw shear-force and bending- moment diagrams, labeling all critical ordinates. MA L. Solution 10.4-3 Select Ry as redundant. (8g), = Deflection at B due to force Rg RELEASED STRUCTURE AND FORCE-DISPLACEMENT RELATIONS (8g)2 ЗЕ FROM COMPATIBILITY EQUATION 17 (SB) = (8g)2 .. RB 7b- EQUILIBRIUM RA = 2qL – RB (1) MA = 2qL? – RgL = --qL² (2) (8g), = Deflection at B due to uniform load q 17qL (8g) * 24EI My Question: HOW DO YOU GET THIS. I know how to solve the problem after this step, but how is this deflection formula derived? Using a table? What is it! Please explain in as much detail as possible!
