Question

. By what reasoning did you come to that conclusion that beam is a flexure member

Answer 1

Explanation:

• No reasoning is required - just the observation. Beams flex when subjected to external load. This is an observation. Based on the above - a beam theory was developed, which quantifies the deflections, curvature and the internal stresses.

• Other than this - beam is just a class of objects. All objects are made from materials which deform when internal stress is developed as a consequence of applied loads. If material deforms - then the overall shape of the object will also change. You can call it flexing. Or bending. Or something else.
