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.

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
