1. The formula's in Load Tables for EXPOSURE and DEFLECTION are:
One Span - Mp= .125wl^2, Mn= .125wl^2, x= .0130wl^4/EI
Two Span - Mp= .125wl^2, Mn= .096wl^2, x= .0092wl^4/EI
Three Span - Mp= .080wl^2, Mn= .107wl^2, x= .0069wl^4/EI
Modulas of Elasticity (E) = 29,500 ksi

2. Allowable uniform loads are determined per the following:
a) Allowable Shear Stress (FV) [AISI c3.2]
b) Combined Bending and Shear [AISI c3.3]
c) Combined Bending and Web Crippling [AISI c3.5]

3. Factors of Safety used to determine uniform loads:
W (Bending) = 1.67
W (Shear) = 1.67
W (Web Crippling) = 1.85

4. Allowances have been made for member Dead Weight.

5. Minimum panel support bearing length = 2.00 in

6. Concentrated load = 150 lb at mid-span, load width = 4 in
Simple Span : Max. Span = 1.989 ft (L/180)
Two Span : Max. Span = 2.332 ft (L/180)
Three Span : Max. Span = 2.485 ft (L/180)
