What is the snow load equation for sloped roofs (balanced)?

The snow load equation for sloped roofs takes into account the effects of both the flat roof snow load and how that load is influenced by the slope of the roof. The correct equation, represented as Ps = Cs * Pf, defines the relationship where Ps is the snow load on the sloped roof, Pf is the flat roof snow load, and Cs is the slope factor that adjusts the flat roof load to reflect the effects of the slope.

In this case, Cs is often derived from building codes or engineering guidelines that indicate how snow loads should be adjusted based on the roof's slope. The slope can allow snow to slide off more easily or concentrate in certain areas, hence requiring this adjustment. By multiplying the flat roof snow load (Pf) by the slope factor (Cs), we achieve a more accurate representation of the snow load that will effectively act on the sloped surface.

Other options provided do not correctly account for the relationship between the flat snow load and the slope adjustment factor. Notably, options that propose combinations or modifications like adding terms or using coefficients without a clear multiplicative structure do not give a correct representation of the snow load as per standard engineering formulas. This makes Ps = Cs * Pf the appropriate choice for reflecting how sloped roofs experience
