Beam Equations

δ = deflection in unit length
a = distance where load is applied from support
P = force
L = total length of beam in unit length
x = distance from support where P is applied in unit length
E = Young’s Modulus
I = Moment of Inertia
M = Moment
σ = Bending Stress
c = Distance from Neutral Axis to Extreme fibers
V = Sheer Stress
