Maximum Torque for Crushing Failure of Bolt Formula Elements

Variables
Maximum Torque
Maximum torque means the highest value of the net torque measured at full engine load.
Symbol: Tm
Measurement: TorqueUnit: N*mm
Note: Value should be greater than 0.
Number of Bolts
Number of Bolts is simply defined as the number of bolts that are under our consideration.
Symbol: n
Measurement: NAUnit: Unitless
Note: Value should be greater than 0.
Diameter of Bolt
Diameter of Bolt is the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
Symbol: db
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Thickness of Flange
Thickness of Flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength or for stabilizing and guiding the movements of a machine or its parts.
Symbol: tf
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Allowable Crushing Strength of the Bolt Material
Allowable Crushing Strength of the Bolt Material is the capacity of a material or structure to withstand loads tending to reduce size as opposed to tensile strength.
Symbol: fcb
Measurement: StressUnit: N/mm²
Note: Value should be greater than 0.
Pitch Circle Diameter of Bolts
Pitch Circle Diameter of Bolts (PCD) is the diameter of the circle which passes through the centre of all the studs, wheel bolts or wheel rim holes.
Symbol: D1
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
