Title: Results of some tests of manila rope
Description: This paper summarizes the results of tensile tests of 368 specimens of manila rope. Most of the material was submitted on purchase orders for Government departments. They were all 3-strand, regular lay manila rope having diameters from 1/2 inch to 41/2 inches. A summary of the results is given in tables and graphically. A formula is given for determining the average breaking load as a function of the diameter of the rope. The test results cover sufficient range and show such consistency that it is believed that the formulas may be used safely for 3-strand, regular lay manila rope of the sizes indicated. The ropes showed a continually varrying modulus of elasticity and no well-defined proportional limit.
