When the trapezoidal distribution load acts on the cantilever beam as shown in the figure, the reaction force R at the point can be obtained as below.

Since only the normal force acts, the force acting on the beam is equal in magnitude to the normal force and reaction force.

If P1 ¡Â P2

R = P1 * L + (P2-P1) * L / 2 = (1/2) (P1 + P2) * L

If P1 ¡Ã P2

R = P2 * L + (P1-P2) * L / 2 = (1/2) (P1 + P2) * L

In both cases the formulas are the same, so both can be used.

*** Âü°í¹®Çå[References] ***

R = (1/2)*(P1+P2)*L
