PROBLEM 7.152*
Determine the sag-to-span ratio for which the maximum
tension in the cable is equal to the total weight of the entire
cable AB.
PROBLEM 7.153*
A cable of weight per unit length w is suspended between
two points at the same elevation that are a distance L apart.
Determine (a) the sag-to-span ratio for which the maximum
tension is as small as possible, (b) the corresponding values
of
θ
Band Tm.
