chapter 7 assignment

1. for each of the following measurements, suggest an appropriate tool and provide a reason for using that tool.

a. a box that is 15 cm long
tool:
reason:
b. diameter of a nut (for a bolt)
tool:
reason:

Explanation:

a. For measuring a 15 - cm - long box, a ruler is suitable as it can measure lengths up to a certain extent (usually 30 cm or more) and is easy to use for such relatively large - scale linear measurements.
b. For measuring the diameter of a nut, a vernier caliper is appropriate. It can measure small dimensions with high precision, which is required for accurately determining the diameter of a small object like a nut.

Answer:

a. Tool: Ruler
Reason: Can measure lengths up to a moderate extent and is easy to use for larger linear measurements.
b. Tool: Vernier caliper
Reason: Can measure small dimensions with high precision.
