We are trying solve for the angular or Sine 382 vector force and we want our answer to be pounds per panel. Panel is 16" wide (1.333 ft) Solving for vector multiply vertical, 35psf times the sine, which is .382, resulting with 13.37 psf To get the units in pounds per panel, we that figure by the length of the roof and the width of the panel The result for this example 978 pounds per panel. So for this example our snow guard system must resist 978 pounds of force pushing against extend
