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

WLL=CBS * DF

RWLL= WLL x EFFICIENCY of KNOT or SPLICE

this is damaging to ropes

weight = volume x density of material

volume = base x height x length

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

weight= volume x density of material

volume= 1152, density = .0184

What is the weight of the following Douglas Fir crossarm of the density is .0184 pounds per cubic inch, with a base of 4.5" height of 5.5" and a length of 10'

Weights of Poles is $$volume\ =\pi\times r^2\times Length$$

Weights of Poles is $$volume\ =\pi\times r^2\times Length$$ density is .0174 pounds per cubic inch, radius is 8 and the length is 65'

As sling angle decrease, tension of slings decreases substantially

sling tension= sling length/sling height x weight/# of slings

sling tension= sling length/sling height x weight/# of slings

length= 14" height=3" weight= 487 lbs 2 slings

What is the HL Tension? Weight = 487# 2parts

Formula is $$HL=1.1^{p\ \times W\div P}$$
