Question

Which of the following is not true about beam bridges? a) They are simple in design b) They have short spans c) Beam bridges are subject to torsional forces d) Beam bridge design prevents shearing forces from affecting it

Answer 1

Beam bridges are subjected to shearing forces, which are forces that act perpendicular to the length of the beam.

Step-by-step explanation:

Out of the given options, the statement that is not true about beam bridges is d) Beam bridge design prevents shearing forces from affecting it. Beam bridges are subjected to shearing forces, which are forces that act perpendicular to the length of the beam. Shearing forces can cause the beam to bend or break if they are too strong. Therefore, beam bridge designs must consider and account for shearing forces.
