This page provides formula for calculating reactions, shear, moments and deflections for a cantilever beam with an end load.
Return to Beam Listing|
Nomenclature:
R = Reaction force
V = Shear force
F = Loading force
M = Moment
l = beam length
x = location
E = Modulus of elasticity
I = Moment if Inertia
y = deflection
Relationships: -------------- R1 = V = F M1 = -F * l M = F * (x - l) y = (F * x^2)/(6 * E * I) * (x - 3 * l) ymax = -(F * l^3)/(3 * E * I) at x = l
