Where:

E =	Modulus of Elasticity	psi	(N/mm2)
I =	Moment of Inertia	in4	(mm4)
W =	Load on Beam	lbs	(N)
s =	Stress at the cross-section being evaluated	Lbs/in2	(N/mm2)
y =	Beam Deflection (Positive Upward Beam Deflection, Negative Downward	inches	(mm)
x =	Some distance as indicated	inches	(mm)
a =	Some distance as indicated	inches	(mm)
v =	Some distance as indicated	inches	(mm)
l =	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.
