Determine the smallest moment of inertia ? required for the beam, so that its max. deflection
does not exceed the limit of 1/240 of the span length (i.e., Δ ≤L/240). Use the moment-area
method.

 

1. Determine the smallest moment of inertia I required for the beam, so that its max. deflection
does not exceed the limit of 1/240 of the span length (i.e., A <L/240). Use the moment-area
method and conjugate beam method. Show your
