Description: The Central Calorimeter and its support cradle are to be supported by either hydraulic or mechanical jacks. If hydraulics are used, each support will use two hydraulically coupled jacks with two out of the four supports hydraulically coupled giving the effect of a three point support system. If mechanical jacks are used, all four points are used for support. Figure 2 shows two examples of jack placement on a 3.5 inch support plate. These two support scenarios lead to five jack failure cases to be studied. This report deals with the way in which a 0.25 inch drop (failed jack) at one support affects the stresses in the cradle. The stresses from each failure case were analyzed in two ways. First, stress factors, defined as quotients of stress intensities of the failed case with respect to the static case, were generated and then, hand calculations similar to those in Engineering Note 3740.215-EN-14 were done using the reaction forces from the failed case.
