## Connector Plate Load Estimate
This notebook calculates an estimate maximum load for the connector plates used in the STM assembly.


```python
from pint import UnitRegistry
unit = UnitRegistry()
unit.formatter.default_format = "~"

preload_m4 = 3000 * unit.N
n_screws = 4 # 2 on each side
friction_coeff = 0.21 # Al on Al
safety_factor = 1.5

max_load = preload_m4 * friction_coeff * n_screws / safety_factor / unit.standard_gravity
max_load.to(unit.kg)
```
