King: Philippine Bast-fiber Ropes 
577 
Ropes made of the strongest and lightest fiber give the highest 
breaking length. However, a rope having a comparatively low 
breaking load (represented by the numerator of the equation) 
but having a relatively small weight per unit length (given by 
the denominator of the equation) would also give a high breaking 
length. Rope possessed of a very high breaking load and a 
relatively high mass per unit length might still give a high 
breaking length. 
Table V. — Breaking lengths of Philippine handmade bast-fiber ropes ayid 
miscellaneous hand- and machine-laid fiber ropes. The same residts, 
arranged in a different order, are given in Table XLII.
