    F(lengte) = 14 x L / #lengte <resultaat in kg>

    F(breedte) = 21 x B / #breedte <resultaat in kg>

    Verklaring:
    F(lengte) (kg) = spankracht voor lengtesnaren
    F(breedte) (kg) = spankracht voor breedtesnaren
    L = lengte binnenblad (cm)
    B = breedte binnenblad (cm)
    #lengte = aantal lengtesnaren
    #breedte = aantal breedtesnaren

    Deze resultaten geven de maximale spankracht (100%).
    Voor het berekenen van een zachtere bespanning haal je resp. 5, 10, 15 of 20% af van het resultaat voor:
    95% hardhitter en spinspeler
    90% mediumhitter
    85% comfortabel of lichte armblessure
    80% korte swing met minder controle of armblessure

    Voorbeeld
    Racket met 18 lengte- en 18 breedtesnaren, lengte binnenblad 33cm, breedte binnenblad 24cm voor een hardhitter:
    F(lengte) = 14 x 33 / 18 = 25,6kg
    F(breedte) = 21 x 24 / 18 = 28kg

    F(length) = 14 x L / #length-strings <result in kg>

    F(width) = 21 x B / #width-strings <result in kg>

    Eplanation:
    F(length) (kg) = tension strength in length
    F(width) (kg) = tension strength in width
    L = length of inner blade (cm)
    B = width of inner blade (cm)
    #length-strings = number of strings in length of blade
    #width-strings = number of strings in width of blade

    These results do calculate the maximum tension (100%).
    To calculate a softer tension, decrease the result with respectively 5, 10, 15 or 20% to:
    95% hardhitter and/or spinplayer
    90% mediumhitter
    85% comfortable of light arm injury
    80% short swing with less control of arm injury

    example
    A Racket with 18 length- and 18 width-strings, length inner blade 33cm, width inner blade 24cm for a hardhitter:
    F(length) = 14 x 33 / 18 = 25,6kg
    F(width) = 21 x 24 / 18 = 28kg

    Note:
    The harder the tension of a string is applied, the more control the hitting of the bal but the less power the ball gets.
    The softer the tension of a string is applied, the less control the ball gets but the more power the ball gets.
