Cantilever Beam - Uniformly Distributed Loadcb 1A

Uniformly Distributed Load Formula

\(\large{ R = V =  wL  }\)

\(\large{ V_x =  wx    }\)       

\(\large{ M_{max} \; }\)   (at fixed end)   \(\large{   =  \frac {w L^2} {2}  }\)

\(\large{ M_x   =   \frac  { wx^2 } {2}   }\)

\(\large{ \Delta_{max} \; }\)   (at free end)   \(\large{   =  \frac {w L^4} {8 \lambda I}  }\)

\(\large{ \Delta_x   =  \frac {w} {24 \lambda I}  \left(   x^4 - 4L^3x + 3L^4   \right)     }\)

 

Where:

\(\large{ I }\) = moment of inertia

\(\large{ L }\) = span length of the bending member

\(\large{ M }\) = maximum bending moment

\(\large{ R }\) = reaction load at bearing point

\(\large{ V }\) = shear force

\(\large{ w }\) = load per unit length

\(\large{ W }\) = total load from a uniform distribution

\(\large{ x }\) = horizontal distance from reaction to point on beam

\(\large{ \lambda  }\)   (Greek symbol lambda) = modulus of elasticity

\(\large{ \Delta }\) = deflection or deformation
