How long is a piece of string?

The engine manufacturer assigns a load factor ratiing to the engine and it states those limitations.

There is normally a "maximum continuous power" number in the specifications. If you want to know why, there are lots of academic studies available that go into great detail on what wears how much and why under different loading conditions.
