Trussed Frames A large majority of the truck frames are now made ofpressed steel, but the frame side members, as a rule, aretapered very little toward the ends, particularly the rearend. This is no doubt due to the different load distribu-tion as compared with a passenger car. The Clydesdalewas the only truck noticed in which there was consider-able taper in the side members. It is rather remarkable that not more trucks have theirframes trussed, as quite a saving in weight could evi-. January 20, 1921 AUTOMOTIVE INDUSTRIESTHE AUTOMOBILE 121
