Shear Pins are common in day to day life. Cranes and aerial lifts use them extensively. 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.

1. Loads P1 and P2 can be applied in opposite directions. Stresses are calculated at either T2 or T3 depending on which moment is higher.
2. A moment on the pin can be expressed as separating a couple into forces P1 and P2.
