Continuous Beams

Continuous beams, which are beams with more than two supports and covering more than one span, are not statically determinate using the static equilibrium laws

e = strain
σ = stress (N/m2)
E = Young's Modulus = σ/e (N/m2)
y = distance of surface from neutral surface (m).
R = Radius of neutral axis (m).
I = Moment of Inertia (m4 - more normally cm4)
Z = section modulus = I/y max(m3 - more normally cm3)
M = Moment (Nm)
w = Distributed load on beam (kg/m) or (N/m as force units)
W = total load on beam (kg ) or (N as force units)
F= Concentrated force on beam (N)
L = length of beam (m)
x = distance along beam (m)
