Increase in length due to expansion Solution

Follow our step by step solution on how to calculate Increase in length due to expansion?

FIRST Step Consider the formula

ΔL Bar = l \cdot α \cdot t

Next Step Substitute values of Variables

∴

ΔL Bar = 1280cm \cdot 1.2E-5°C⁻¹ \cdot 30°C

Next Step Convert Units

∴

ΔL Bar = 12.8m \cdot 1.2E-5K⁻¹ \cdot 30K

Next Step Prepare to Evaluate

∴

ΔL Bar = 12.8 \cdot 1.2E-5 \cdot 30

Next Step Evaluate

∴

ΔL Bar = 0.004416m

LAST Step Convert to Output's Unit

∴

ΔL Bar = 4.416mm
