Total Number of Turns of Engine Valve Spring given Maximum Compression in Spring Formula Elements

Variables
Total Coils in Valve Spring
Total Coils in Valve Spring is the total number of coils or turns of spring including the coils at the ends of the spring.
Symbol: Nt
Measurement: NAUnit: Unitless
Note: Value should be greater than 0.
Modulus of Rigidity of Valve Spring
Modulus of Rigidity of Valve Spring is the elastic coefficient when a shear force is applied resulting in lateral deformation. It gives us a measure of how rigid a body is.
Symbol: G
Measurement: StressUnit: N/mm²
Note: Value should be greater than 0.
Wire Diameter of Valve Spring
Wire Diameter of Valve Spring is the diameter of the wire of a valve spring, which constitutes the coils of the spring.
Symbol: dw
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Maximum Compression in Valve Spring
Maximum Compression in Valve Spring is the maximum amount of axial deflection in the valve spring.
Symbol: x
Measurement: LengthUnit: mm
Note: Value should be greater than 0.
Axial Force on Valve Spring
Axial Force on Valve Spring is the force acting at the ends of spring trying to compress or expand it in the axial direction.
Symbol: P
