A columns critical load is the maximum compressive load that it can support without buckling. Any additional load will cause buckling. Good column designs are circular tubes. Also, other shapes with I x.

Friday, March 26, 2010. Combined Loadings - Mechanics of Materials. Combined Loadings - Stress analysis of axial load, torsion, bending, and shear. Cross sections with several internal loads that occur all at once. This type of tank will be subjected to 2 normal stresses, both in tension.

Saturday, April 24, 2010. Deflection of Beams - Mechanics of Materials. Showing the slope and displacement for a beam when loading is applied. Often called the deflection diagram, showing the elastic curve. This curve is fairly simple to sketch just knowing simple restrictions for the slope and displacement. Supports such as a pin or a roller will resist a force and therefore will restrict displacement.

Monday, April 26, 2010. Mechanical Properties of Materials - Mechanics of Materials. A materials strength is its ability to have an applied load and resist deformation. This is the elongation of the material, L and L o. Are distances between the marks after and before elongation. Where P is the applied load and A o.

Friday, June 25, 2010. Processes and Materials in Manufacturing.

Sunday, April 11, 2010. Stress Transformation - Mechanics of Materials. Transforming stress components from one set coordinate system to a coordinate system with a different orientation. Will be positive if it points up on the right side of the element.
