_______________________ is the process of taking something apart and analyzing its workings in detail, usually with the intention of understanding its structure, function, and operation.

a)

Engineering

b)

Reverse Engineering

c)

Mechanical Technician

d)

Diagnostics

20.

When starting reverse engineering, you first must do a non-destructive analysis to: identify the purpose of the product, make hypotheses of how the product works, and list inputs and outputs. What is this non-destructive analysis?

a)

Visual Analysis

b)

Function Analysis

c)

Structural Analysis

21.

Disassembly or tear down of a product is a major step in the reverse engineering process, it uncovers the principles behind how a product works. It is always fun to tear apart a product, but nothing will be accomplished if data is not collected during the process. To gather this data, we will use ________________________________.

a)

Gantt chart

b)

product disassembly chart

c)

concurrent engineering table

d)

a workflow chart

22.
This is a process where a product is disassembled, uncovering principles behind how a product works. Data is collected to determine how parts interact, what the good and bad features of the product are, what manufacturing process was used, and what caused the product to succeed or fail.
a)
Reverse Engineering
b)
Visual Analysis
c)
Functional Analysis
d)
Structural Analysis
