Step 1

Refer the given figure, the given figure is symmetry and loaded as equilibrium. help_outlineImage TranscriptioncloseSo the reaction force at point A and B are equal gL R R3 2 М, %3 М, Thus, the reaction force are R R3 Calculate the bending moment from the right end of the beam M Rx- M 2 -- М, + (Lx .(1) 2 (ck-x7)7 fullscreen
Step 2

Write the differential equation for the fixed end beam. help_outlineImage TranscriptioncloseLx-x) Elv" = M -M + Integrate both side with respect to x Elv'=-Mx+ 2 C 3 (2) 2 Again integrate and apply the boundary condition.
