Crane Manufactures Asso. of America (CMAA) 70 Question
(OP)
I want to use the allowable stresses listed in 3.4 Allowable Stresses for a calculation. However, for clearification, in CMAA 70 the far right column of listed allowables, 3.4.1, 3.4.2, and 3.4.3, is "Allowable Bearing Stress" the same as bending stress?





RE: Crane Manufactures Asso. of America (CMAA) 70 Question
1 - Bending Stress is related to flexing of a beam - you need section modulus to calculate the stress.
2 - Bearing stress is related to the area under compression at the support of a shaft. If it is too high you will crush the bearing material - be it white metal, bronze bush, polyurethane, or whatever.
