Consider a 2-D object consisting of two triangle compartments, as shown in Figure P9.4. Suppose a solution containing a 511 KeV gamma ray emitting radionuclide with concentration f = 0.5….
cut the blank from paper and verify that the tray is As such, the important factors are bendability, and scoring such as shown in Fig. 7.71
The design shown in the accompanying illustration is proposed for a metal tray, the main body of which is made from cold-rolled sheet steel. Noting its features and that the sheet is bent in two different directions, comment on relevant manufacturing considerations. Include factors
such as anisotropy of the cold-rolled sheet, its surface texture, the bend directions, the nature
of the sheared edges, and the method by which the handle is snapped in for assembly.
By the student. Several observations can be made. Note that a relief notch design, as shown
in Fig. 7.68 on p. 405 has been used. It is a valuable experiment to have the students cut
the blank from paper and verify that the tray is As such, the important factors are bendability,
and scoring such as shown in Fig. 7.71 on p. 406, and avoiding wrinkling such as discussed
in Fig. 7.69 on p. 405.
