The material of the stud is given in the title plateas cold rolled steel and that of the armature head as soft steelcasting. The front view is shown in section on line A-B-C. Thecareful reader will note that section line A-B-C follows thevertical center line of the right side view from A at its loweredge to B at the center axis and then slants to the right andupward, following the center line of one of the three ribs to C. Stud. A study of the front and the end views shows that thestuds (D (also shown at the upper right of the blueprint) arescrewed into the three ribs just mentioned, and a lettered noteplaced on the sectioned front view states that they are machinedto a bevel after assembling. 48 THIRD ANGLE.
