If there is a gap of 3/8" (9 mm) that requires shims, how many shims do you need?
Understanding the Problem
To solve this problem, we need to understand the concept of shims and how they are used to fill gaps. Shims are thin pieces of material, usually metal or plastic, used to fill small gaps between two objects. In this case, we have a gap of 3/8" (9 mm) that requires shims.
Calculating the Number of Shims
To calculate the number of shims needed, we need to determine the total thickness of the shims required to fill the gap. Let's analyze the options:
- Option A: Two 1/4" (6 mm) and one 1/8" (3 mm)
- Option B: Three 1/8" (3 mm)
- Option C: One 1/2" (12 mm) and one 1/8" (3 mm)
- Option D: All of the above
- Option E: None of the above
Analyzing Option A
Let's start by analyzing Option A. Two 1/4" (6 mm) shims would have a total thickness of 2 x 6 mm = 12 mm. Adding one 1/8" (3 mm) shim would give us a total thickness of 12 mm + 3 mm = 15 mm. This is greater than the required gap of 9 mm.
Analyzing Option B
Now, let's analyze Option B. Three 1/8" (3 mm) shims would have a total thickness of 3 x 3 mm = 9 mm. This is equal to the required gap of 9 mm.
Analyzing Option C
Next, let's analyze Option C. One 1/2" (12 mm) shim would have a total thickness of 12 mm. Adding one 1/8" (3 mm) shim would give us a total thickness of 12 mm + 3 mm = 15 mm. This is greater than the required gap of 9 mm.
Analyzing Option D
Option D states that all of the above options are correct. However, we have already analyzed each option and found that only Option B is correct.
Analyzing Option E
Option E states that none of the above options are correct. However, we have already analyzed each option and found that Option B is correct.
Conclusion
Based on our analysis, the correct answer is Option B: Three 1/8" (3 mm) shims. This is the only option that provides a total thickness equal to the required gap of 9 mm.
Mathematical Proof
Let's prove our answer mathematically. Let x be the number of 1/8" (3 mm) shims needed. Then, the total thickness of the shims is 3x mm. We want to find the value of x such that 3x = 9 mm.
Dividing both sides by 3, we get:
x = 9 mm / 3 x = 3
Therefore, we need 3 shims, each with a thickness of 1/8" (3 mm).
Real-World Applications
This problem has real-world applications in various fields, such as:
- Engineering: Shims are used to fill gaps between machine parts, ensuring proper alignment and function.
- Construction: Shims are used to level floors and walls, ensuring a stable and secure structure.
- Automotive: Shims are used to adjust the alignment of vehicle parts, such as the engine and transmission.
In conclusion, the correct answer is Option B: Three 1/8" (3 mm) shims. This problem requires a basic understanding of mathematics and the concept of shims.
