1. 10 Reciprocating engines. Relate the post-crash condition of an engine's exhaust manifold to the post crash condition of light bulb flament in terms of temperature, failure modes, and engine operation at impact. Il the engine exhaust manifold was hot at impact. then the manifold might be bent or crumpled (ductile behavior) from ground impact. This would tend to indicate the engine was running at impact. O If the engine exhaust manifold was hot at impact, then the manifold might show signs of brittle metal or fracture-type failures from ground impact. This would tend to indicate the engine was running at impacti If the engine exhaust manifold was cold at impact, then the manifold might show signs of brittle metal or fracture-type failures from ground impact. This would tend to indicate the engine was not running al impact. If the engine exhaust manifold was cold at impact, then the manifold might be bent or crumpled (ductile behavior) from ground impact.
