Free Expansion of Steel Solution

Follow our step by step solution on how to calculate Free Expansion of Steel?

FIRST Step Consider the formula

ΔL s = α T \cdot ΔT rise \cdot L bar

Next Step Substitute values of Variables

∴

ΔL s = 1.7E-5°C⁻¹ \cdot 85K \cdot 2000mm

Next Step Convert Units

∴

ΔL s = 1.7E-51/K \cdot 85K \cdot 2m

Next Step Prepare to Evaluate

∴

ΔL s = 1.7E-5 \cdot 85 \cdot 2

Next Step Evaluate

∴

ΔL s = 0.00289m

LAST Step Convert to Output's Unit

∴

ΔL s = 2.89mm
