Essential Calculations

I recently had to replace a tatty hedge with a tidy fence. I wanted to build a fence that created a visual barrier but allowed the wind through. To do this I made a structure of 'Yorkshire Board' but put the boards at an angle to make best use of the timber.

To do that I created a spread sheet that determined the length of each board and how many I would get from each plank to give me a fence 42 inches high. The resulting columns of figures suggested the I should include the boards at 20 degrees from the vertical and by doing so I would loose a couple of inches from each 15 foot length.

The columns above are :-

A - Degrees

B - Degrees converted to Radians

D & E - Sin & Cosine (of the angle)

G - The length of each board (42 / COS angle + 6 * SIN angle)

I - No of board (Plank length / board length)
