Multiple choice

The two shafts AB and BC, of equal length and diameters d and 2d, are made of the same material. They are joined at B through a shaft coupling, while the ends A and C are built-in (cantilevered). A twisting moment T is applied to the coupling. If TA and TC represent the twisting moments at the ends A and C, coupling respectively, then

  1. TC = TA

  2. TC = 8TA

  3. TC = 16TA

  4. TA = 16TC
