Figure 4

The die with the cemented coping was inserted into a specially designed testing device (left drawing). The washer was located under the horizontal top bar shown above and the die protruded through that bar. A metal pin (P) was inserted through a metal band and a hole drilled through the die. That attachment is shown in the central drawing. The 300.0 mm long metal band was attached to the universal testing machine that generated a recordable force (in the direction of the arrow shown in the figure). The metal band and the attachments are shown in the reduced drawing to the right.
