Question:

The bracket shown in figure 5.24 consists of a rigid arm and a flexible rod. The latter has the following properties: moment of inertia $I=1.0$, polar moment of inertia $J=0.5$, radius $r=0.1$, length $l=10.0$, and yield stress $\sigma_{Y}=2.8$. When a vertical force of $F=1.0$ is applied at the end of the rigid $\operatorname{arm}(a=5 \sqrt{2})$, calculate the stress matrix at point $A$, and evaluate the safety factors at that point using both the distortion energy theory and maximum shear stress theory.
