deltaL= L * coeff thermal expansion Al * delta Temp

What is the linear expansion for 1 Deg F change in a piect of aluminum that is 1.9 inches long?

To find the linear expansion for a 1-degree Fahrenheit change in a piece of aluminum, you need to know the coefficient of thermal expansion for aluminum.

The coefficient of thermal expansion is a measure of how much a material expands or contracts as a result of a temperature change. The coefficient of thermal expansion for aluminum is approximately 0.000013 inch/inch/°F.

The formula to calculate the linear expansion is given as:

deltaL = L * coeff thermal expansion * delta Temp

where:
deltaL is the change in length
L is the original length
coeff thermal expansion is the coefficient of thermal expansion
delta Temp is the change in temperature

Given:
L = 1.9 inches
coeff thermal expansion for aluminum = 0.000013 inch/inch/°F
delta Temp = 1 °F

Plugging the given values into the formula, we have:

deltaL = 1.9 inches * 0.000013 inch/inch/°F * 1 °F

Calculating this expression will give us the linear expansion for a 1-degree Fahrenheit change in a piece of aluminum that is 1.9 inches long.
