Previous on MSXII, the shear pin used was (believed) to be 4-5mm nylon pin, therefore, it would be suitable for MSXIV to also use a nylon pin, from calculations above, the nylon pin should be between 5.35 to 6mm in diameter. A diameter of 5.5 mm was chosen and the pin will be machined out of 1/4” OTS nylon rod.
Verification
Scenarios | Force (N) |
|---|---|
Pulling on steering wheel | 225 |
Average body weight of 20+ year male | 890 |
Average torque generated by steering (500ms) | 2100 |
...
All three forces are below 1575N with SF of 2, therefore the pin is not expected to fail with normal handling.
