PROBLEM 7.161
For the beam shown, draw the shear and bending-moment diagrams,
and determine the magnitude and location of the maximum absolute
value of the bending moment, knowing that (a) M = 0, (b) M = 24
kip ∙ ft.

PROBLEM 7.162
The beam AB, which lies on the ground, supports the
parabolic load shown. Assuming the upward reaction of the
ground to be uniformly distributed, (a) write the equations of
the shear and bending-moment curves, (b) determine the
maximum bending moment.
PROBLEM 7.163
Two loads are suspended as shown from the cable ABCD.

1.8 m,
B
d=
determine (a) the distance
,
C
d
(b) the components of the reaction at D, (c) the maximum
tension in the cable.
PROBLEM 7.164
A wire having a mass per unit length of 0.65 kg/m is suspended from two supports at the same elevation
that are 120 m apart. If the sag is 30 m, determine (a) the total length of the wire, (b) the maximum
tension in the wire.
PROBLEM 7.165
A 10-ft rope is attached to two supports A and B as shown. Determine (a) the
span of the rope for which the span is equal to the sag, (b) the corresponding
angle θB.
