The safe working load can be calculated using the 6 x 19 &. 6 x 36 classification.
The safe working load for a 1 diameter IWRC 6 19 wire rope can be calculated by 6 x 19 &. 6 x 36.

Whoever told you this is whacky. Why would you think this is true?
Line is a nautical term for a rope. But a rope can be a line attached on only one end in normal use. The bell rope, the bucket rope, the tiller rope, the bolt rope, check rope, foot rope, monkey rope, and the dip rope.
The maximum area that you can contain with a 4-meter rope is a circle with a diameter of 4/π meters and an area of 4/π square meters, or about 1.273 square meters. If you use the rope to make an equilateral triangle with sides of 4/3 meter, you get an area of (4/9)(√3) or 0.770 square meters. If you use the rope to make a square with sides of 1 meter, you get an area of 1.000 square meter. If you make a polygon with more sides, the area bounded by your 4-meter rope will increase, approaching the limit of 4/π as the number of sides increases.
a rope clock is nothing but
TO CALCULATE THE SWL OF LIFTING WIRE ROPE THE FORMULAE CAN BE USED- 8*D2 WHERE 'D' IS THE DIAMETER OF WIRE ROPE IN 'mm' THIS WILL GIVE THE APPROX SWL (SAFE WORKING LOAD CAPACITY)
Density of steel is taken as 7850 kg/cum. Hence unit weight of 50mm dia steel rope will be approximately 15.42 kg/m.

These are rule of thumb formulas but close to a manufacture's chart. for fiber core wire rope square the diameter times 42 = NBS Example, 1/2" x 1/2" x 42 = 10.5 tons UBS (Ultimate breaking strength) or NBS The formula is the same for IWRC, but use 45 as the multiplier, because of the higher strength in the rope. Example, 1/2" x 1/2" x 45 = 11.25 ton
a multiplier of 5
To convert breaking strain to safe working load you must establish a safety factor (SF). Assume SF of 10. If a line has a breaking strain of 1 tonne then you should only suspend or load the line to a strain of 100Kg (1000Kg/10) A common SF for normal use is 6. If human loads are in use then SF 10 is more common.
Think of a tensile load as a "pulling" force. A tensile load is the only type of load that can be taken by a rope, for instance.
The load arm is the radius of the pulley. This is the distance from the fulcrum to the load-carrying side of the rope.

AnswerDoubling the thickness of the rope means the diameter is doubled.Since the strength is directly proportional to the diameter square,then the strength will be more by four times.
