Where:

E =	Modulus of Elasticity	psi	(N/mm²⁾
I =	Moment of Inertia	in⁴	(mm⁴⁾
l =	Length of Beam	inches	(mm)
W =	Total Load on Beam	lbs	(N)
p =	With Line Pressure Load	psi-in	(N/mm)
s =	Stress at the cross-section being evaluated	Lbs/in²	(N/mm²⁾
y =	Beam Deflection	inches	(mm)
x =	Some distance as indicated	inches	(mm)
Z =	section modulus of the cross-section of the beam = I/z	in³	(mm³⁾
z =	distance from neutral axis to extreme fiber (edge)	inches	(mm)

Please note letter "l" (lower case "L") is different than "I" (Moment of Inertia).
Deflections apply only to constant cross sections along entire length.
