overhangs that extend in both directions for a distance of 4.2 m
from the supports at B and C, whiich are 1.2 m apart.
Draw the shear-force and bending-moment diagrams for this
overhanging beam. 10.6 kN/m

simple beam at A and B (see figure). A cable passes over a small pulley
that is attached to the arm at E. One end of the cable is attached to the
beam at point B. The tensile force in the cable is 1800 lb.
Draw the shear-force and bending-moment diagrams for beam ABCD.
(Note: Disregard the widths of the beam and vertical arm and use centerline dimensions when making calculations.) E 1800 lb Cable
