6.8 SHAFTS UNDER SPECIAL CONDITIONS
Under certain special field conditions, the shafts may have varying cross sections, may be made out of two or more materials and may be subjected to varying torque.
6.8.1 Shafts of Varying Sections
In the case of shafts of different lengths and of different diameters, the torque transmitted by individual sections are calculated first. The strength of the shaft is governed by the minimum value of these torques.
6.8.2 Shafts of Different Materials
Shafts made out of different materials are called as composite shafts which behave as a single shaft. In this type of shafts, one type of shaft is rigidly sleeved over another type of the shaft. The total torque transmitted by a composite shaft is the sum of the torque ...
