Question 1: A bolt extends 5/16 inch on each side of a plate that is 1 1/2 inches thick. What is the total bolt length needed?
- 2 1/8 inches (Correct answer)
- 2 inches
- 1 7/8 inches
- 2 1/4 inches
Correct answer: 2 1/8 inches
5/16 + 1 1/2 + 5/16 = 10/16 + 24/16 = 34/16 = 2 1/8 inches.

- 7/8 inch (Correct answer)
- 3/4 inch
- 5/6 inch
- 9/10 inch
