Question

A beam ABCD with a vertical arm CE is
supported as a simple beam at A and D (see figure
part a). 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.

(a) What is the force P in the cable if the bending
moment in the beam just to the left of point C

is equal numerically to 7.5 kN?m? Note: Dis-
regard the widths of the beam and vertical arm

and use centerline dimensions when making
calculations.
(b) Repeat part (a) if a roller support is added at C
and a shear release is inserted just left of C (see
figure part b).
