Solve problem 5/137. Answer to problem 5/136 is m = 270 kg, length AC = 79.1 m

5/136 A cable weighing 25 newtons per meter of length is
suspended from point A and passes over the small pulley at
B. Calculate the mass m of the attached cylinder which will
produce the sag of 9 m. Also determine the horizontal dis-
tance from A to C. Because of the small sag-to-span ratio,
use the approximation of a parabolic cable.
