TEST KEY:

1. Which of the following tools is not a layout tool.

A. square

B. saw

C. blender

D. planer

C. blender

2. Name three layout tools that could be used for linear measuring.

Tapes, folding rules and scales are three possibilities. Others mentioned in the text include squares, scratch awls, calipers and dividers.

3. What layout tool would be best for measuring the circumference of a round object?

Tape

4. Which would be more accurate -- a steel tape or a cloth tape? Why?

A steel tape would be more accurate. When numbers and lines, called gradations, are stamped into steel tools, they stay readable for a long time. Cloth tapes are not very accurate because they stretch under stress and moisture.

5. Why must you be careful when working with tapes and folding rulers?

Special care must be used when working with tapes because they break if pulled out too far, forced back into the case or bent excessively. Also, care should be taken when opening and closing folding rules, because they will break if they are twisted wrong.

6. Which material is generally more durable for measuring tools?

A. Aluminum
B. Cloth
C. Plastic
D. Steel
E. Wood

Correct answer: D. Steel

7. Which material is tough and light but can melt at high temperatures?

A. Aluminum
B. Cloth
C. Plastic
D. Steel
E. Wood
