Consider a small section of a beam and identify two planes m and n a unit distance apart. Apply a uniform Bending Moment M to this section of the beam. The planes m and n remain plane (assumption 2) but are now inclined at an angle to one another. https://s3-euw1-ap-pe-df-pch-content-public-u.s3.eu-west-1.amazonaws.com/9781315272559/7bbb1d56-80f2-4a95-aaf5-7d36cc2dbba5/content/page_133.tif"/>
