Problem $3$: Snow Load Calculation $(25$ pts$)$

Using the NBC $2020,$ the snow load calculation videos, and Tutorial $6$:

a$)$ Determine the snow load $($in kPa$)$ for a building of normal risk category in Sault Ste. Marie, ON$,$ with a flat, non$-$slippery roof measuring $\backslash (40\backslash$mathrm$\{$~m$\}\backslash$times $40\backslash$mathrm$\{$~m$\}\backslash ),$ with no obstructions. The building is$.$ considered to be in an exposed area in a rural zone.

b$)$ Find the snow load distribution $($in kPa$)$ on the lower roof of the office building shown in Figure $3,$ located in Sault Ste. Marie, ON$.$ The building can be considered under "sheltered" conditions.

c$)$ How will the snow distribution in question $\backslash (2$ b $\backslash )$ be affected if the building is now in exposed conditions? Explain by showing the snow distribution for this case.
