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

STEP 0: Pre-Calculation Summary
Formula Used
Diameter of Spigot = (4*(Mean Width of Cotter^2)*Bending Stress in Cotter*(Thickness of cotter)/Load)-(2*Diameter of Socket Collar)
d2 = (4*(b^2)*σb*(tc)/L)-(2*d4)
This formula uses 5 Variables
Variables Used
Mean Width of Cotter - The mean Width of Cotter is defined as the average width of the cotter of a cotter joint. (Measured in Millimeter)
Bending Stress in Cotter - Bending Stress in Cotter is defined as the stress that is induced in the cotter subjected to loads that cause it to bend. (Measured in Newton per Square Millimeter)
Thickness of cotter - Thickness of cotter is the measure of how much broad is the cotter in direction perpendicular to axial force. (Measured in Millimeter)
Load - Load is basically the amount of load/force any material, product, joint, can bear or is acted upon or exerts. (Measured in Newton)
Diameter of Socket Collar - Diameter of socket collar is the external diameter of collar of the socket of a cotter joint. (Measured in Millimeter)
STEP 1: Convert Input(s) to Base Unit

## Sleeve and Cotter Joint

The sleeve and cotter joint is a type of joint used to typically connect two similar coaxial cylindrical rods. It includes a sleeve and two wedge-shaped tapered cotters. Appropriate slots are cut in the sleeve and in the cylindrical rods.
Rectangular rods and dissimilar cylindrical rods cannot be connected using this joint. A sleeve and cotter joints do not allow angular misalignment between its cylindrical members. It cannot connect cylindrical members which undergo rotation.
