Answer the following statement(s) true (T) or false (F)
1. An inner boundary (of an internal feature of size) is a worst-case boundary generated by the smallest feature of size (LMC) minus the effects of the applicable geometric tolerance and any additional tolerance (bonus) that may apply. 2. An outer boundary (of an external feature of size) is a worst-case boundary generated by the largest feature of size (MMC) plus the effects of the applicable geometric tolerance. 3. When a feature control frame is associated with a feature, it applies to a surface and does not affect the worst-case boundary. 4. If geometric tolerances at RFS are applied to an external feature of size, the worst-case boundary is called the inner boundary. 5. Where a geometric tolerance at MMC is applied to an external feature of size, the worst-case boundary is called the virtual condition boundary (MMC).
All of the following statements are true EXCEPT:
A. spray washers have skimmers to remove oily contaminants from the surface of the solution. B. sludge can be neutralized and solidified with chemicals so that it can be disposed as nonhazardous waste. C. alkaline cleaning will remove rust and scale, but acid cleaners will not. D. sandpaper is sometimes used to clean machined surfaces but should not be used on bimetal engines that have super smooth head and block surfaces.
During the Renaissance, scientist/artist/engineers developed rules that would explain the perspective that their right brains understood quite naturally, and the system of nonlinear perspective was invented.
