# Homework, Quizzes, Simulation Examples – Stress and Local Equilibrium – Lesson 7

### Simulation Examples

Several simulation examples are provided here. Each of them comes with a description file, video instructions, and Ansys simulation file. All of the simulations were conducted using Ansys software. Download the student version of Ansys simulation software here.

#### (1) Toy drone blade

Review each stress component and equivalent stress over the toy drone blade.

### Homework

Conduct an analysis of a circular bar under torsional load at both ends. Extract the stress tensor components and principal stresses of a point on the bar and write them in a matrix format. What's the relationship between these numbers? What's the coordinate system of the stress tensor and the principal stress?
