Where:

E =	Beam Modulus of Elasticity	psi	(N/mm2)
I =	Beam Moment of Inertia	in4	(mm4)
L =	Length of Beam	inches	(mm)
F =	Loading Point	lbs	(N)
Mn =	Beam Moment Calculated	psi-in	(N-mm)
WL =	Distributed Load Amplitude	Lbs/in2	(N/mm)
Wa =	Distributed Load Amplitude	Lbs/in2	(N/mm)
y =	Beam Deflection	inches	(mm)
an =	Some distance as indicated	inches	(mm)

• Deflections apply only to constant cross sections along entire length.
