Entrainment of an inertial reference frame by an accelerated gravitating shell

For the example of an accelerated shell we show that omission of the energy-momentum tensor (EMT) of the body that causes the acceleration and the tensions due to this acceleration can lead to a paradoxical result; Namely, the entrainment of an inertial frame by the accelerated shell in the direction opposite to that of the acceleration. We consider several models and demonstrate that the correct result can be obtained only if all components of the full EMT are adequately taken into account, and the problem statement is physically correct.
