Graphs from Strain Gauges

### Overview:
- We can create the following graphs using strain guages:
steering torque vs. microstrain and axial stress vs. microstrain
### Research:
- Create the GitHub Wiki page Strain Guages:
- Find conversions and formulas.
- Find which strain gauges correspond to each type of strain.

Start with the requested GitHub Wiki page, “Strain Guages,” and research the conversions and formulas for steering torque versus microstrain and axial stress versus microstrain. Document which strain gauges correspond to each strain type; done means the wiki page contains these formulas, conversions, and gauge mappings.
