Beam bridges support weight or load on them by compressing to the area of the load pushing on the beams and the beams creating a reaction force that pushes back up on the load.
The Neutral Axis of a concrete beam is that axis where it is neither in tension nor compression. The transition of tensile to compressive forces set up due to bending occurs on the neutral axis. Its...
need more info. Don't know it is that you want for sure. A load bearing beam is any beam that supports weight bearing down or suspended from it. The name says it all. Need to know exactly what it is...
The upper part of the mantle called the asthenosphere is the layer on which the earth's lithosphere (crust plus uppermost rigid mantle) rides.This soft layer serves as support for the crust to float...
