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.

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.
