(a) Obtain a formula for the fixed-end moments MA and MB in terms of the load q, the length L, and the length b of the loaded part of the beam. (b) Plot a graph of the fixed-end moment MA versus the length b of the loaded part of the beam. For convenience, plot the graph in the following nondimensional form: MA 2 qL /12 versus B A MB MA RA a b L b L with the raio b/L varying between its extreme values of 0 and 1. (c) For the special case in which a b L /3, draw the shear-force and bending-moment diagrams for the beam, labeling all critical ordinates. Solution 10.4-24 Fixed-end Beam FROM EXAMPLE 10-4, EQ.
