Chapter 20, Problem 26P
Answer the following questions regarding material condition modifiers.
(a) What are the three material condition modifiers?
(b) Which one is the default if nothing is specified?
(c) Which one(s) can provide “bonus” tolerance?
(d) Which of the following is increased by a bonus tolerance? (Select one.)
- i. A size dimension.
- ii. A ± tolerance of a size dimension.
- iii. A basic dimension locating a feature.
- iv. A size of a tolerance zone controlling a feature.
(e) To which of the following can a material condition modifier symbol be applied? (Select one.)
- i. A size dimension.
- ii. A ± tolerance of a size dimension.
- iii. A tolerance of a geometric characteristic controlling a feature of size.
- iv. A tolerance of a geometric characteristic controlling any feature.
(f) Which material condition modifier should be considered if the goal is to ensure a minimum clearance fit for a bolt in a hole, but to give greater manufacturing flexibility if the hole is produced with a greater clearance?
(g) Which material condition modifier should be considered if the goal is to provide a consistent press fit between interchangeable parts?
(h) Which material condition modifier should be considered if the goal is to ensure a minimum wall thickness for a casting, but to give greater manufacturing flexibility if the wall is produced with a greater thickness?

In the context of our teaching, which one of the
below statements is mostly correct about in
detailed design of a component?
In the reporting, I do not need to include the
reasoning for my design decision for a good
quality report.
I cannot use appendix, so I am struck with the
word limit for reporting.
For a good clarity, I should not explicitly
report what are the key dimensions and their
tolerances in the drawing and in the body of
text.
The word count limit for detailed design
report is 160O.
