Unit Four - Modeling

Unit 3 - Overview

Define your understanding of the term Reverse Engineering, and identify the three stages in reverse engineering.

Reverse engineering is the process of dissembling something in an attempt to understand its components, function, and design. This understanding can be put towards recreating the object, or using the object's technology to improve other technologies. The three stages of reverse engineering are visual analysis, functional analysis, and structural analysis.

3 things you learned in regard to the Tolerance / Clearance

Tolerance is an acceptable amount of dimensional variation that will allow an object to function correctly.
Clearance is the amount of space between two mating parts.
Tolerance can be given in in specified dimension & tolerance, limit dimensions, and general tolerance forms.

Engineering design ethics: Give two examples of the importance of the practice of engineering ethics

Ethics can help us protect our future from technologies that benefit us only in the short term, such as fossil fuel usage. If we properly apply ethics, we can insure long term success.
Ethics must be used in the creation of products to ensure they do not break in such a way to pose potential risks. An example of a failure to apply ethics in this way was the Chernobyl disaster, which resulted from a lack of proper security procedures, and mismanagement from the workers.

Unit 3 - Reflection

What are the advantages of using computer aided design for holes?

By using CAD, we can insure that any holes are precise and standardized.

What is the difference between accuracy and precision?

The difference between accuracy and precision is that accuracy is the degree of closeness of measurements to the actual value, while precision is the degree to which repeated measurements show the same result.
