the average force in pounds needed to break a rope

• WLL

• CBS

• RWLL

the maximum load applied to a rope to ensure longevity of that rope

• WLL

• CBS

• RWLL

is an arbitrary number used to determine the working load limit

WLL=CBS * DF

• TRUE

• FALSE

RWLL= WLL x EFFICIENCY of KNOT or SPLICE

• true

• false

this is damaging to ropes

• shack load

• slack load

• snap load

• shock load

weight = volume x density of material

• false

• true

volume = base x height x length

base = 3", height = 4", length= 96"

• 1101 cu.in.

• 1251 cu.in.

• 1152 cu.in

• 1098 cu.in.

weight= volume x density of material
