Lugs to Lifting Beams
Lifting lug of steel is visible and hand-touchable. The lug conveys the force from the hook to the lifted body. The lifted weight cannot see, but it can calculate. When lifting, the weight converts to potential energy. The energy used to lift process and it consists of potential energy and machinery losses.
The deformation of the lifting lug is proportional to lifted weight, without telling the amount of the used power. This is because, by knowing the power in time unit, the total time or lifted height is not known. Time does not affect to strength of the lifting lug. It is affected by the number of repetitions. On the other hand, repetions can not determine by examining the lug.
History backwards: The Big Bang generated 80% hydrogen and 20% helium. Percentages should pay attention to, because this ratio affects a number of issues. For example, the ratio of right and left-handed people. As an introduction to the factor of 1.25, in general 20 % corresponds to 80 % of all events.
100/1.25 = 80 40/80 = 0.25
The collapse of stars generated nuclear fusion and new elements such as iron and is therefore everywhere in the universe. Iron is a chemical element, including the mathematical proportionality. The calculation is based on the S235 and S355 strength class steels, which closely have the strength ratio of Golden Ratio 1.618. Calculated ratio S355 / S235 = 1.51
It is good start the design work by planning first the lifting lugs. Once I heard the supervisor's instruction, at a tank manufacturer's premises; "do first the needed lifting lugs". This, because a designer had forgotten lifting lugs. The problem was how to turn the tank construction, without lifting lugs. Previous sounds humorous, but think it more about.
