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.

To calculate the safe working load for a flexible wire rope, you need to consider factors such as the diameter of the rope, the material it is made of, the construction (number of strands and wires per strand), and the type of load (static or dynamic). The safe working load is typically specified as a percentage of the breaking strength of the wire rope, with industry standards recommending values ranging from 5% to 20% of the breaking strength depending on the application and safety factors. It is important to follow manufacturer guidelines and consult relevant standards when calculating the safe working load for a wire rope.
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)
The weight per meter for a 32mm 6x29FI IWRC steel wire rope is approximately 9.47 kilograms per meter. This figure may vary slightly depending on the specific manufacturer or tolerances. It is important to consult the manufacturer's specifications for precise measurements.

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

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.
The minimum breaking load of a wire rope refers to the minimum load required to break the rope under laboratory conditions. It is important to consider this specification when selecting a wire rope for lifting or pulling applications to ensure safety and optimal performance. The minimum breaking load is typically expressed in tons, pounds, or kilograms depending on the standard used.
Wire rope load capacity can be calculated by considering factors such as the breaking strength of the wire rope, the design factor for the specific application, and any additional safety factors required. The formula typically used is: Load capacity = (Wire rope breaking strength / Design factor) - Weight of the load. It is crucial to consult industry standards and guidelines when determining load capacity to ensure safety and reliability.
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.
