Extension of Rod if Rod is Free to Extend Solution

STEP 0: Pre-Calculation Summary

Formula Used

Increase in Bar Length = Initial Length*Coefficient of Thermal Expansion*Temperature Rise
ΔL_Bar = l₀*α_T*ΔT_rise
This formula uses 4 Variables

Variables Used

Increase in Bar Length - (Measured in Meter) - The Increase in Bar Length refers to the elongation of a bar resulting from a change in temperature.
Initial Length - (Measured in Meter) - Initial Length is the original, unaltered length of a bar or material before any changes, such as thermal expansion or contraction, occur.
Coefficient of Thermal Expansion - (Measured in Per Kelvin) - The Coefficient of Thermal Expansion is a material property that is indicative of the extent to which a material expands upon heating.
Temperature Rise - (Measured in Kelvin) - Temperature Rise is the increment in temperature of a unit mass when the heat is applied.

STEP 1: Convert Input(s) to Base Unit

Initial Length: 5000 Millimeter --> 5 Meter (Check conversion here)
Coefficient of Thermal Expansion: 1.7E-05 Per Degree Celsius --> 1.7E-05 Per Kelvin (Check conversion here)
Temperature Rise: 85 Kelvin --> 85 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ΔL_Bar = l₀*α_T*ΔT_rise --> 5*1.7E-05*85

Evaluating ... ...

ΔL_Bar = 0.007225

STEP 3: Convert Result to Output's Unit

0.007225 Meter -->7.225 Millimeter (Check conversion here)

FINAL ANSWER

7.225 Millimeter <-- Increase in Bar Length
