Nominal Diameter of Tappet or Stud of Rocker Arm of Engine Valve Formula Elements

Variables
Constants
Functions
Nominal Diameter
Nominal Diameter is defined as the mean or average outside diameter of a profile.
Symbol: DN
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Gas Load on Exhaust Valve
Gas Load on Exhaust Valve is the amount of force acting on the inner side of the exhaust valve due to the back pressure or cylinder pressure when the exhaust valve opens.
Symbol: Pg
Measurement: ForceUnit: N
Note: Value should be greater than 0.
Inertia Force on Valve
Inertia Force on Valve is the force acting opposite to the direction of valve motion onto the valve.
Symbol: P
Measurement: ForceUnit: N
Note: Value should be greater than 0.
Spring Force
Spring Force is the force exerted by a compressed or stretched spring upon any object that is attached to it.
Symbol: Ps
Measurement: ForceUnit: N
Note: Value should be greater than 0.
Compressive Stress in Tappet
Compressive Stress in Tappet or stud is the force per unit area that is responsible for the deformation of the tappet such that the volume of the material reduces and its length decreases.
Symbol: σc
Measurement: StressUnit: N/mm²
Note: Value should be greater than 0.
Archimedes' constant
Archimedes' constant is a mathematical constant that represents the ratio of the circumference of a circle to its diameter.
Symbol: π
Value: 3.14159265358979323846264338327950288
sqrt
A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number.
