Answer the following statement(s) true (T) or false (F)
1. In some cases, it is desired to have an unequal distribution of the tolerances between the clearance holes and the threaded holes. In these cases, the total amount of tolerance resulting from the fixed fastener formula is distributed unequally. 2. When using the floating fastener assembly, after the position tolerance zone value is calculated, it applies to each part in the assembly (if the clearance holes are the same hole size used in the formula). 3. When using the floating fastener assembly, since the function is assembly, the MMC modifier is used in the tolerance portion of the position callout. This allows additional location tolerance as a hole departs from MMC. 4. The fixed and floating fastener formulas are useful tools for a quick way to establish tolerance values. Additionally, they also account for the typical fastener deviations. 5. Both common types of typical fastener deviations can cause the fastener body to interfere with the surface of the clearance hole in a bolted assembly.
