Method: Joules.tensile_strain

Defined in:
lib/joules/stress_strain.rb

.tensile_strain(extension, length) ⇒ Float

Calculates the tensile strain given extension and length.

Examples:

Joules.tensile_strain(2, 10) #=> 0.2

Parameters:

  • extension (Int, Float) —

    extension >= 0; extension is in metres

  • length (Int, Float) —

    length > 0; length is in metres

Returns:

  • (Float) —

    return value >= 0

Raises:

  • (ZeroDivisionError) —

    if length = 0
