Definition and Theory
Buckling is defined as an instance of lateral bending or bowing of the column shape due to a compressive load on a column. There are three basic types of column failures. One, a compressive material failure, i.e., the material cracks or crumbles. This type of column failure usually happens to columns that are very short and fat. Two, a buckling failure, i.e., lateral bending or bowing of the column shape. This type of column failure usually happens to columns that are very long and skinny. Three, a combination of both compressive and buckling failures. This type of column failure occurs when length and width of a column is in between a short and fat and long and skinny column. (P) is the compressive load that causes buckling to occur. Buckling for this experiment is defined when the lateral change from a straight line to the curve is equal to the ratio (D) is equal to (L) / (H) = 24; record the load at this point. We are using this ratio to so we can compare column buckling of various lengths. As the length decreases, the horizontal distance (H) decreases.
