Beam Stress and Deflection Calculations for Non-Engineers

Rectangular Cantilever Beam in Direct Compression and Bending:

Rule 1: For every calculated normal stress there is a corresponding induced shear stress; the value of the shear stress is equal to half that of the normal stress.

Rule 2: For every calculated shear stress there is a corresponding induced normal stress; the value of the normal stress is equal to that of the shear stress. The tables of combined stress formulas, below, include equations for calculating both maximum nominal tensile or compressive stresses, and maximum nominal shear stresses.

Where:

L =	Length of Beam	inches	(mm)
h =	Height of Beam	inches	(mm)
b =	Width of Beam	inches	(mm)
Fy =	Applied Load	lbs	(N)
Fx =	Applied Load	lbs	(N)
σ' a =	Stress, Tensile or Compressive	Lbs/in2	(N/mm2)
σ' b =	Stress, Tensile or Compressive	Lbs/in2	(N/mm2)
τ'a =	Stress , Max. Nominal Shear	Lbs/in2	(N/mm2)
τ'b =	Stress , Max. Nominal Shear	Lbs/in2	(N/mm2)
