ASME BTH-1 clearly defines rules for material selection and determining what kind of load would be permitted by the design in question. According to BTH-1 calculations, the short beam can be loaded to full yield strength (accounting for safety factors), but as the beam length (or lifting spread) increases, the stress reaches an inflection point where the allowable bending stress starts to drop off. In the latest revision of BTH-1 (2017), there are three design categories, categories A, B and C, as well as five different services classes, service class 0 through 5.
