Bending stress in cotter of cotter joint Solution

STEP 0: Pre-Calculation Summary
Formula Used
Bending Stress in Cotter = (3*Load/(Thickness of cotter*Mean Width of Cotter^2))*((Diameter of Spigot+(2*Diameter of Socket Collar))/12)
σb = (3*L/(tc*b^2))*((d2+(2*d4))/12)
This formula uses 5 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)
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)
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)
Diameter of Spigot - The diameter of Spigot is defined as the diameter of the external surface of the spigot or the inner diameter of the socket. (Measured in Millimeter)
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
Load: 5250 Newton --> 5250 Newton No Conversion Required
Thickness of cotter: 10 Millimeter --> 0.01 Meter (Check conversion here)
Mean Width of Cotter: 30 Millimeter --> 0.03 Meter (Check conversion here)
Diameter of Spigot: 45 Millimeter --> 0.045 Meter (Check conversion here)
Diameter of Socket Collar: 100 Millimeter --> 0.1 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σb = (3*L/(tc*b^2))*((d2+(2*d4))/12) --> (3*5250/(0.01*0.03^2))*((0.045+(2*0.1))/12)
Evaluating ... ...
σb = 35729166.6666667
STEP 3: Convert Result to Output's Unit
35729166.6666667 Pascal -->35.7291666666667 Newton per Square Millimeter (Check conversion here)
FINAL ANSWER
35.7291666666667 Newton per Square Millimeter <-- Bending Stress in Cotter

Socket and Spigot Cotter Joint

A cotter joint knows as a socket and spigot joint, is a method of temporarily joining two coaxial rods, one end of the rod provided with a socket type and the other end of the other rod inserted into the socket. The end of the rod goes into a socket also called a spigot.
A rectangular hole is built into the socket and spigot. A cotter is tightly operating through a hole to make a temporary connection between the two rods. The load is usually acting axially, but it changes its direction. And so, the cotter joint should design to carry both tensile and compressive loads. Compressive load taking by the caller on the spigot.
