Q.

A simply supported laterally loaded beam was found to deflect more than a specified value. Which of the following measures will reduce the deflection?

A. Increase the area moment of inertia

B. Increase the span of the beam

C. Select a different material having lesser modulus of elasticity

D. Magnitude of the load to be increased

Answer & Explanation

Deflection of simply supported is inversely proportional to area moment of inertia.

Thus correct option is: A.
