# Foundations in Stress Analysis using Ansys Mechanical - Simulation Quiz 2

### Exhaust Manifold Analysis

An exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. It gets exposed to extreme heating and cooling, which causes constant expansion and contraction. Manifolds can crack over time due to the stress from such constant and intense temperature changes. In this problem, we will see how the thermal stresses and strains develop when the manifold reaches a temperature of 300 °C.
