## 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)
|
|
```
