Material And Cross Section Geometry Essays
Results and Description
Several observations were noted during the course of the experiment. It was noted that although the dial indicator measured a deflection in each beam when weights were added, there was no visible change in the beams (No stress or strain was observed). It was also noted that the weight holder would shift positions or rotate when weights were added.
The dimensions for each of the four beams tested were recorded in Table 1. “b1” represents the base, which is the width of the beam. “h1” is the height of the beam. These were found by measuring the outermost cross section of each beam. “h2” and “b2” only apply to the fourth beam, the aluminum box, and were found by measuring the dimensions of the inner cross section.…
