    For me the terms need to be spelled out: effective length (if helix resting on table but standing vertically is length the height?) Also what angles are pitch and alpha?

  • @Harish $n$= standing length ( or height of helix)/pitch.

If you unroll the cylinder the helix winds around, you have a right triangle with the hypotenuse the helix, one leg the number of circumferences of the cylinder that corresponds to the number of turns and the other leg the height along the cylinder.

    $displaystyle begin{array}{{>{displaystyle}l}}
    Let, Radius= R\
    Pitch= P\
    Effective length of helix= L\
    And Number of turns= N\
    First of all we should calculate the length associated with one turn within the helix. Let it be x.\
    Now formula for x is
    end{array}$



    $displaystyle $ $displaystyle x^{2} =P^{2} +( Circumference)^{2}$



    $displaystyle begin{array}{{>{displaystyle}l}}
    Where Circumference= 2πR. Hence x=sqrt{P^{2} +( 2πR)^{2}}\
    And number of turns, N=frac{L}{x}\
    or N=frac{L}{sqrt{P^{2} +( 2πR)^{2}}}
    end{array}$
