Is there any evidence to indicate that either gas is preferable? Use o. = 0.05. Question Three An experiment was run to determine the abrasive wear of three different laminated materials. The samples used were either oven dried or moisture saturated. The machine ran for a fixed amount of time, and the depth of bearing was recorded as follows: 1= 1 N - 6 Wear, in * 10-3 C = 3 Materials A B C 38 35 Irt 5= 2 Heat Treatment Oven Dried 44 Moisture Saturated 32 42 35 86 Determine whether: PTC ? = 1719 6 i) Wear characteristic of the three materials are different ETY= 2557 0 ii) The heat treatment affect wear iii) The interaction between materials and the heat treatments are significant.
