1. Shown in Fig. P.11.67 is a cantilever beam with a triangular loading distribution. For a yield stress of 4 x 108 Pa and a modulus of elasticity of 2 x 1011 Pa, what is the maximum loading wo for an elastic behavior criterion and for a limit-design criterion? Neglect the effects of the weight of the beam.
2. What is the maximum stress in the section A-A from the load P = 1000 Ib (see Fig. P.11.67)? Use curved beam theory and compare results with that from straight beam theory.
