SHEAR, MOMENT AND DEFLECTION OF BEAMS

SIMPLE SUPPORTS - MOMENT LOAD

Nomenclature:
R = Reaction force
V = Shear force
M = Moment
l = beam length
x = location
a = Distance from right support to moment
b = Distance from left support to moment
E = Modulus of elasticity
I = Moment if Inertia
y = deflection

Relationships:
--------------
R1 = -R2 = MB / l
V = MB / l
MAB = MB * x / l
MBC = MB / l * (x - l)
yAB = (MB*x) / (6*E*I*l) * (x^2 + 3*a^2 - 6*a*l + 2*l^2)
yBC = MB / (6*E*I*l) * (x^3 - 3*l*x^2 + x*(2*l^2 + 3*a^2) - 3*a^2*l)
