Loading_Factor

Loading_Factor(Load$)

Function Loading_Factor returns the endurance limit modification factor associated with type of load (The Marin factor k_c).

Input:

Load$ - string indicating the type of load

 'Axial' = axial load

 'Bending' = bending load

 'Torsion' = torsional load

Output:

Returns the dimensionless endurance limit modification factor associated with load.

Example:  

$Load Mechanical Design

Load$='Axial' 

k_c=loading_factor(Load$)

{Solution:

k_c = 0.85}
