Generalize the results of Prob. 1731 by representing the factor of safety n as n = ad/(b/m)
Question:
Generalize the results of Prob. 17–31 by representing the factor of safety n as
n = ad/(b/m) + cd2
Where m is the number of ropes supporting the cage, and a, b, and c are constants. Show that the optimal diameter is d* = [b/(mc)]1/2 and the corresponding maximum attainable factor of safety is n* = a[m/(bc)]1/2/2.
