Abstract:  
This paper discusses the benefits derived from shot peening and prestressing torsion bar springs for track type vehicles. Prestressing is defined by the author as "the application of a controlled overload to produce permanent set in members in which the strains vary across the section". It is considered to be especially valuable where the loads are of considerable magnitude and in only one direction.
