Abstract:  
In certain engineering structures weight is of paramount importance. The problem is really two-fold: 1) The excessively stressed areas must be located and remedied to achieve sufficiently long life. 2) The low stressed areas must be located and lightened to achieve least weight. This leads to a concept of design efficiency, namely performance per unit weight. Applying this concept to a magnesium truck wheel, this paper discusses: 1) The advantages of magnesium over steel. 2) The use of stresscoat and strain gages to locate and measure the strains in the wheel during actual truck maneumers. 3) The fatigue analysis and performance evaluation. 4) The relative merits of testing-to-failure methods and experimental stress analysis techniques.
