It is quite complicated to determine the strength of each material used in the engineering field. Although the principle is simple as to learn the exact amount of load a particular material can handle or withstand, parameters leading to the identification of this is difficult to attain.

In order to do this, engineering stress is used to determine the strength of materials. Stress as defined is the ratio of the force applied to the material at its cross sectional area. Different kinds of stress have been analyzed although most of the time, load transfer is just a minor alteration to the formula. The more critical parameter to analyze is the cross-sectional area on where the force is applied, which usually depends on which kind of stress is being studied.
