Thickness of cotter joint given bending stress in cotter Solution

STEP 0: Pre-Calculation Summary
Formula Used
Thickness of cotter = ((2*Diameter of Socket Collar)+(Diameter of Spigot))*((Load)/(4*(Mean Width of Cotter^2)*Bending Stress in Cotter))
tc = ((2*d4)+(d2))*((L)/(4*(b^2)*σb))
This formula uses 5 Variables
Variables Used
Diameter of Socket Collar - Diameter of socket collar is the external diameter of collar of the socket 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)
Load - Load is basically the amount of load/force any material, product, joint, can bear or is acted upon or exerts. (Measured in Newton)
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)
STEP 1: Convert Input(s) to Base Unit
Diameter of Socket Collar: 100 Millimeter --> 0.1 Meter (Check conversion here)
Diameter of Spigot: 45 Millimeter --> 0.045 Meter (Check conversion here)
Load: 5250 Newton --> 5250 Newton No Conversion Required
Mean Width of Cotter: 30 Millimeter --> 0.03 Meter (Check conversion here)

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.
