# V. Tee Shaped Cantilever

To find the stress due to an applied moment at the free end of a cantilever beam with inverted tee section.

## Reference

Hand calculation using the following reference:

Crandall, S.H., and Dahl, N.C., An Introduction to the Mechanics of Solids, McGraw-Hill, Inc., 1959, Page 294, Problem 7.2..

## Problem

Find the maximum bending stress in the beam of length L with due to moment, M, and the free end.

 E = 30×(10)6 psi

 L = 10 in.

 M = 1,000,000 in.·lb.

## Comparison

Table 1. Comparison of results
