Show A TREND TO LIGHTNESSI LIGHTNESSOne LIGHTNESS LIGHTNESSOne I One of the most interesting mteretmg . , tendencies in engineering engmeermg in all alliields allfields allfields iields fields today is that towaid towmd toward greater lightness hghtness . . The f fact ct that re- re reduction reduction re reduction - duction m ill weight is accompanied by no loss of strength , , reliabi reliabi- reliability reliability reliability - lity arid and ana anaendurance endurance makes it all the moie more mOl e interesting and im- im important important im important - portant . .
