Conduit Offset Brain Fart

[lorddrago]

What is the formula for calculating the multiplier for conduit offset?

 

[infinity]

Multiplier = 1/sin of angle

i.e.: 1/sin 30? = 1/.5=2

or just make a chart of the most common degrees of bend on most benders:

-----------offset multiplier---------------shrink per inch of offset rise
10?-----------5.76-----------------------------.0625, 1/16"
22.5?---------2.62-----------------------------.1875, 3/16"
30?-----------2.00-----------------------------.250, 1/4"
45?-----------1.4142--------------------------.375, 3/8"
60?-----------1.1547--------------------------.500, 1/2"

Then memorize it:happyyes:

Multiplier = 1/sin of angle

i.e.: 1/sin 30? = 1/.5=2

1/sin z = csc z , where csc is the cosecant function.
