Notes:
1. The bending moment calculated will exist in members 1 and 2 as well as the pin at the pinning location.
2. If the pin is not fixed to at least one side, there will be edge loading on members 1 and 2. This nullifies the bearing area stress calculations.
3. Whenever possible, use a pin that eliminates the gap (i.e. a bolt). This allows the moment to be transfered from member 1 to member 2.
4. Whenever possible, use a double shear design to minimize the moment.

Shear Pins are common in day to day life. A better choice is a double shear pin, but single shear does have it’s place. This simple calculator allows you to get the stresses on the pin and bearings quickly with out headaches.

Unlike other online calculators, this calculator allows for gaps and calculates the bending moments on the pin.
