Question

Scantron - Multiple Choice True/False General knowledge from lab section of course Practice Problems 1. 2. 3. 4. A section view cannot replace one of the three standard orthographic views when used in a drawing When considering geometric tolerance, the Nominal Size and the Basic Size are never the same value An interference fit guarantees that there will be space or "wiggle room" between the two mating parts It is acceptable to dimension to hidden lines A part has a dimension "Q." That dimension has a tolerance of +0.003 inches, and so is displayed as Q±0.003. We refer to this style of tolerance as a non-uniform bilateral tolerance Dimensions should be drawn to "L" shaped features on the drawings, instead of "T" shaped ones. Parametric equations allow you to dimension a feature as a function of another feature's dimension An object line is a line for features that are present on the part, but are not viewable in the current orientation because of other material blocking the viewer's line of sight. 5. 6. 7. 8.

Answer 1

1. True : Section views can replace the normal top, front, side, or other standard orthographic views in the standard view arrangement.

2. False : between a shaft (or bolt) going through a hole in some other part (such as a nut), both the shaft (or bolt) have the same nominal size (also called the basic size) but all the holes are physically larger and all the shafts are physically smaller in order that any shaft (or bolt) of a given nominal size can fit into any hole of the same nominal size.

3. False : The fit that never leaves space between the mating parts.

4. False : There is no need to dimension hidden lines.

5. False : Its is considered as an uniform bilateral tolerance.

6. False : Doesn't depend on features.

7. True : Parameric functions define assosciaton as a function of another dimension.

8. True : object lines (solid), depict features of the actual object
