Cantilever with Elastic and Plastic Behaviour

In Fig. P10.29 is shown a cantilever beam, subjected to axial and lateral loads and made from a material that has an elastic, perfectly plastic constitutive law with Y = 60,000 psi. See attachment for diagram.
a. What is the largest value of qo for elastic action throughout?
b. What is the largest value of qo, allowing for plastic behaviour?
c. What is the minimum value of qo so that the bottom fibers just begin to yield? What are the depths of plastic penetration d1 and d2 for a load qo that is 1.1 times the value just calculated.


Solution Summary

This solution contains step-by-step calculations and explanations to determine the value of 'qo' for elastic action, plastic behaviour, and when the bottom fibers begin to yield.
