Hi
Consider a symmetrical beam, where as we know the Neutral Axis (NA) would be at the Geometric Center. If that beam was simply supported at both ends, there would be equal tension and compression to ensure that beam was in equilibrium.
Now if we applied a vertical load, downwards, in the center, the beam would sag and be in compression at the top and tension on the bottom. My question is: Would the NA move to accommodate the increase in tension on the bottom surface? If it doesn't, how can this be, as tension has increased?
Thanks in advance...
