ENB205 Lecture Notes - Parallel Axis Theorem, Gyration, Ultimate Tensile Strength
Document Summary
A combination of resistant bodies arranged so that by their means the mechanical forces of nature can be compelled to do work accompanied by certain determinate motions. Not be confused with the area moment of inertia. This same theorem also works for area moments of inertia in the same way. This intuitively seems like it should be ( that is not the case. V = poisson"s ratio (~0. 3 for most metals) Static load a stationary load that is gradually applied having an unchanging magnitude and direction. Failure a part is permanently distorted and will not function properly. A part has been separated into two or more pieces. Material strength: sy =yield strength in tension, sys=yield strength in shear, su = ultimate strength in tension, suc = ultimate strength in compression, sus =ultimate strength in shear =. 67 su. Ductility is measured by % elongation at the fracture point. Materials with 5% or more elongation are considered ductile.
