Three engined ferry flights, (my experience was BAe146), call for the two symmetrical engines to be set at take-off thrust, and the third engine must only be 'throttled up' above a certain airspeed.)
In the DC-10 & MD-11, i believe an engine-out ferry w/ #2 inop could present a related problem: Rapid power up on #1 & #3 might create enough nose-up moment to diminish or lose nosewheel steering effectiveness.

It's a case of the thrust line being well below the center of mass.
