Angular defleciotn in shafts8/30/2023 ![]() ![]() Table 10-2 should also be consulted prior to making allowance for keyways. It is noted that this is equivalent to a stress concentration factor of 1.33. The code also applies a factor of 0.75 to the calculated design stress if the section being considered includes a keyway. For combined stresses, as discussed in Section 10.4, the shear design stress is used. The smaller of the two computed stresses is to be used. ![]() According to this code, the basic design stress shall be: The ''Code of Design of Transmission Shafting, 11 which has been published by the ASME as code B 1 7c, 192 7, gives the basic factors to be used in determining the design stresses, either normal or shear. However, it must be modified to account for various loading anomalies. The design stress is obtained from the yield strength of the material to be used. ![]() The value to be used for the design maximum shear stress, f s.max, is discussed in the next section.ฤก0.5 Design Stresses and Load Variations for Transmission Shafting Where f s and f are obtained from the relations given in Section 10.3. ![]()
