## Diameter of spigot of cotter joint given shear stress in spigot Solution

STEP 0: Pre-Calculation Summary
Formula Used
Diameter of Spigot = (Load)/(2*(Gap between End of Slot to End of Spigot)*Shear Stress in Spigot)
d2 = (L)/(2*(a)*τ)
This formula uses 3 Variables
Variables Used
Load - Load is basically the amount of load/force any material, product, joint, can bear or is acted upon or exerts. (Measured in Newton)
Gap between End of Slot to End of Spigot - Gap between End of Slot to End of Spigot is the distance between the end of slot for cotter to the end of spigot opposite from its collar. (Measured in Millimeter)
Shear Stress in Spigot - Shear Stress in Spigot is the amount of stress (cause deformation by slippage along a plane parallel to the imposed stress) generated into the socket due to the shear force acting on it. (Measured in Newton per Square Millimeter)
STEP 1: Convert Input(s) to Base Unit
Load: 5250 Newton --> 5250 Newton No Conversion Required
Gap between End of Slot to End of Spigot: 8 Millimeter --> 0.008 Meter (Check conversion here)
Shear Stress in Spigot: 14 Newton per Square Millimeter --> 14000000 Pascal (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
d2 = (L)/(2*(a)*τ) --> (5250)/(2*(0.008)*14000000)
Evaluating ... ...
d2 = 0.0234375
STEP 3: Convert Result to Output's Unit
0.0234375 Meter -->23.4375 Millimeter (Check conversion here)
23.4375 Millimeter <-- Diameter of Spigot

### Diameter of spigot of cotter joint given shear stress in spigot Formula

Diameter of Spigot = (Load)/(2*(Gap between End of Slot to End of Spigot)*Shear Stress in Spigot)
d2 = (L)/(2*(a)*τ)

## Loads supported by a cotter joint.

Cotter joints are used to support axial loads between the two rods, tensile or compressive. Although a cotter joint will resist the rotation of one rod relative to the other, it should not be used to join rotating shafts. This is because the cotter will not be balanced and may work loose under the combination of vibration and centrifugal force.
