7HomeworkMatch rope materials to their descriptions. Write the correct letters on the blanks.16. Strong, hard fiber from the abaca plant; type #1 best for rope and identified by a colored string twisted into the fibers; short, non-continuous strands provide poor tensile strength17. Synthetic rope with three to three and one-half times the tensile strength of manila, but may lose up to 15 percent of its strength when wet; stretches under load so is not suitable for vehicle stabilization or similar applications18. Synthetic fiber sometimes known as Dacron®; particularly suitable to high-strength, low-stretch applications such as vehicle stabilization; very susceptible to damage by alkalis19.

40GENERAL INFORMATION ABOUT KNOTS The ability to tie knots is a vital part of fire and rescue operations.Synthetic rope material has changed methods of selecting and tying knots:Manila and other natural fiber ropes are no longer considered safe for life safety use.Synthetic rope is slick and may slide under load, so it requires an overhand or half hitch safety knot on the working end.The bends in knots weaken rope: outside fibers are stretched; inside fibers are bent or crushed.
