VIDEO TRANSCRIPT

This is Giancoli Answers with Mr. Dychko. Strain is the change in length of something that's been squished divided by its original length and we can multiply both sides by l naught for original length and you get that the change in length is strain times original length. And so from the previous problem, we found that the strain in this marble column is 3.5 times 10 to the minus 6 so we multiply that by 8.6 meters to get 3.0 times 10 to the minus 5 meters which is about 30 micrometers.
