Labels:signaling device | sky OCR: The Vertical Weight of Snow is reduced by the sine of the roof angle To arrive at the angular force that acts on snow guard The vertical weight of snow translates into "drag loadr The snow guards must resist this drag load or be torm from their mounting we can quantify this drag load (or vector force) that pushes against the snow guards, then we know exactly what force must be resisted by the guard. The drag load or vector force is related to but less than the total vertical weight of the snow bank It is also related to the slope of the roof. To solve for this force we reduce the design vertical weight of snow by the sine of the roof angle The result the angular force or vector load that acts upon snow guard. 70
