    Re: Pole Lengths and Crossing Height.

    Hi Guys

    I get the following:-

    C1=D/(1/TanA4+1/TanA3)= 33.08821294
    P3 67.55902076
    P4 67.43208235
    P4 crossover 38.49859273
    P3 crossover 44.87892315

    Do you agree?

    Regards

    Luke

    Also please find attached "horror" spreadsheet which I have been using!
    The worksheet "Input and Answer Display Q2" is used for entering and display of answers. Worksheet "Calculations Query2" is used for the working steps. I am struggling with "Calculations Query1" to determine how to get length for P3. I am sure the diagram will cause amusement!

    Hi Luke,
    You can't keep adding new problems (changing values and questions). Post your new problem.

    My apologies. As the questions/problems all relate to the same area I have kept it in the same thread. I will raise a new post. Thanks Luke
