a greater load before deflecting. The direction of the deflection is greatly dependent of the consistency of the material and cross section. If there are any imperfections along a given cross section on the material, the deflection will occur in that direction. The shape of the column is also of great importance. The values for moment of inertia are dependent on the shape of the

material. This in turn means that the critical buckling load varies according to the shape of the material being tested. The length of the column is also important because the longer the column is, the less load it will be able to handle before deflecting. This leads into the significance of the column end boundary conditions. Depending on how the column is supported, the length of the column being used in the calculation of the critical buckling load will vary accordingly. As seen by the graph of load vs. deflection, lateral deflection is a non-linear function. This is known because the slope of the graph is constantly changing and does not create a straight line. The information found in this experiment proves that the hypothesis was correct, in that material, cross-sectional area, and length of the column will affect the values for the critical buckling load and the direction of deflection. Remarks: The standard deviations show that the data was fairly accurate.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
