Week 2 Flashcards
What are the three most common types of rope?
Natural fiber
Synthetic fiber
Wire rope
What term defines the free end of a rope used to form a knot?
The running end
How do you calculate the working load limit for a rope?
Catalog breaking strength divided by design factor
What is the efficiency rating of a bowline knot and what is it used for?
65%, making a temporary eye in the rope, greatest quality is it can easily be untied after supporting heavy strain
What is the OSHA requirement for the number of full tucks for a short splice?
Eight full tucks – four on each side of the centerline of the splice is the minimum requirement to achieve the full efficiency of the splice
Which type of splice is best used to join two ends of rope that will be required to pass through a block, especially if tension is involved?
Long splice
When finishing an eye splice, what is the minimum number of full tucks required by OSHA?
Four full tucks is the minimum requirement to achieve the full efficiency of the splice
When referring to rope, what is dynamic loading?
Exposing a rope to severe conditions like: shock loading (quickly snapping tight under heavy loads), excessive use, exposure to high temperatures and extended periods of time under load
Explain what working load limit is.
The maximum load, pulling, or tension forces that should ever be applied to a rope
Explain what Catalog Breaking Strength is
The average force, in pounds, needed to break a rope
