      Exercise 5.—Draw, half size, a plan and section of a double riveted lap joint for plates ⁷⁄₈ inch thick to the dimensions given in the above table.

      Exercise 6: Single Riveted Butt Joints.—In fig. 4 are shown single riveted butt joints. One of the sectional views shows a butt joint with one cover plate or butt strap; the other sectional view shows the same joint with two cover plates; the third view is a plan of both arrangements. Draw all these views full size.
