What does breaking strain, breaking-load and tensile strength mean?
Breaking strain (Fmax) and breaking-load are two names for the same property. The breaking strain of a fishing line describes the amount of force that a line can pull before it breaks e.g. 10 kg. We use the term „(Fmax)”. The correct unit for force is actually N (Newton). 9.81 Newton = 1kg, but this is somewhat depending on one’s geographical position. Kilogram is actually the unit of weight and depends on the strength of gravity. For example, an object that weighs 1kg on earth would weigh slightly less in some places on earth and a lot less in outer space (weightlessness). A force, however, stays the same no matter where it is exerted. But as there aren’t many fish on the moon it’s okay to rate line strength in kg or lb. The tensile strength (Rm) of a line is the result of dividing the breaking strain (Fmax) with the area of its cross section (S). This results in (Rm = Fmax / S) and is expressed in kg/mm2. Conversely, it’s easy to work out the breaking strain (Fmax) of a line, by mult
