Chapter 5, Problem 5/137 A cable weighing 23 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 8.3 m. Also determine the horizontal distance from A to C. (a) Use the approximation of a parabolic cable. (b) Use the exact equations A Answers: (a) Using parabolic approximation m = (b) Using exact equations m = 103 m B 11.2 m C 8.3 m kg, AC- m kg, AC = m m
