      Computation of total applied moment using formula:

Case 1 - Top mounted fixture

In above formula, only variables [1] through [4] are used variables [5] through[7] are not aplicable.

Case 2 - Double cross arm mount

In above formula, only variables [1] through [4] and [7] are used variables [5] through[6] are not aplicable.

Fixture weight on each side is balanced. Do not use [5] X [6].

Case 3 - Single cross arm mount

In above formula, all variables are used.
