Introduction to Strength Calculation
Many people write about strength, so there is no need to repeat what is known. Therefore, we look at things from a perspective that has been ignored. It is hoped that the reader will master the definition of strength. The following is still largely a repetition of what has been written, because everything ultimately means the same thing.
E = m c2
When designing products, it is good to understand the universal laws of matter. For example, consider the result of a bending calculation formula in graphical form. The calculation results given by the formula form a curved line. The formulas provide information about one bending point at a time
f = 5 x F x L3 / ( 384 x E x I )

Something known Something not known
EP Calculation is a type of balance that relies on the use of leverage to determine value. In the context of a hand scale, the things that are weighed are conceptual values. Consider rocks and a bag of sand. Of these, we place the rock on one side of the scale. Sand is placed on the other side of the scale until the scale is balanced. Without needing to know the weight of the rock, we have determined the equivalent mass of sand. Knowing the weight of the rock, calculating the amount of sand would not make sense. Many things are like sand, which is determined by comparison to something known.
