What happens when a beam is heated but cannot expand?
Thermal stress develops!
When expansion is restricted, internal stress is generated in the beam.
👉 σ = E α ΔT
Where:
E = Young’s modulus
α = coefficient of thermal expansion
ΔT = temperature change
This is critical in bridges, rails, and structures exposed to temperature changes.
