What size of manila line is required to hold a weight of 932 lbs., if you use a safety factor of six? Your Answer :: 3.0? Correct Answer :: 2.5? what is the solution of this
Load = 932 pounds
Safety Factor = 6
Find:
Size of the Manila rope
Solution:
Since the unit of weight is pounds, the formula for Manila rope's breaking strength would be C² × 900, where C is the circumference. So, BS = C² × 900.
We can solve for the Manila rope's size by using this formula:
SWL = BS
SF
So by transposition we can have BS = SWL x SF
C² × 900 = SWL x SF
C² × 900 =932 x 6
C = √932 x 6
900
C = √5592
900
C = √6.21333
C = 2.49265 or simply put 2.5" is the final answer.
