Fy = Specified minimum yield stress
E = Modulus of elasticity of steel = 29,000 ksi (200 000 MPa)
Mn = The nominal flexural strength
λr = Limiting width-to-thickness parameter for noncompact element
λp = Limiting width-to-thickness parameter for compact element
...
The design flexural strength =
Mathinline body $$ \normalsize \phi_bM_n $$ The allowable flexural strength =
Mathinline body $$ \normalsize M_n/\Omega_b $$
