Stresses and deflections in truck side rail attachments. Paper presented at the International Automotive Engineering Congress, Detroit, Michigan, January, 13-17, 1969.

Although the carrying capacity of truck side rails is directly related to their cross sectional properties, and limited thereby, they must be adequately positioned and stabilized by "attachments" if their full potential is to be realized. Furthermore, while the capacity of a truck frame cannot exceed the capability of its rails, such value is sometimes not achieved. Frame rails do fail at lesser values, at points other than maximum bending stress.
