16 ; Problem 10.4-9 Beam ABC is fixed at support A and rests (at point B)
upon the midpoint of beam DE (see the first part of the figure). Thus,
beam ABC may be represented as a propped cantilever beam with an
overhang BC and a linearly elastic support of stiffness k at point B
(see the second part of the figure).
The distance from A to B is L 10 ft, the distance from B to C is
L/2 5 ft, and the length of beam DE is L 10 ft. Both beams have
the same flexural rigidity EI. A concentrated load P 1700 lb acts at
the free end of beam ABC.
Determine the reactions RA, RB, and MA for beam ABC. Also, draw
the shear-force and bending-moment diagrams for beam ABC, labeling
all critical ordinates. E P A
