consists of two beams (AD and DE) joined by a hinged connection at D.
The hinge can transmit a shear force but not a bending moment. The loads
on the beam consist of a 4-kN force at the end of a bracket attached at
point B and a 2-kN force at the midpoint of beam DE.
Draw the shear-force and bending-moment diagrams for this
compound beam. 4 kN 1m B C 1m A E 2m Solution 4.5-30 2 kN
D 2m 2m 2m Compound beam Problem 4.5-31 The beam shown below has a sliding support
at A and an elastic support with spring constant k at B.
A distributed load q(x) is applied over the entire beam. Find all
support reactions, then plot shear (V) and moment (M) diagrams
for beam AB; label all critical V & M values and also the
distance to points where any critical ordinates are zero. MA y
