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. |
