3) Record the ultrasonic length “L

” of the sample bolt at the above

minimum temperature - 48

Repeat step 1 - 3

at the target temperatures (T

through T

) – 48, 68,

88, and 108

F (other similar range with 5 temperatures), measuring the

ultrasonic lengths (L

through L

) respectively. This process must be

done for each of the sample bolts in the experiment.

5) Use the equation below to calculate a linear regression, using the

temperatures and lengths recorded for all the sample bolts to determine

the temperature factor.
