Purpose
The purpose of this assignment is to give students experience in measuring objects using a dial caliper, a measurement tool that is far more precise than a standard ruler. This skill is useful when one is reverse engineering an object, especially when recreating that object with the exact dimensions on a 3-D modeling software. Being able to measure objects to a very precise degree is pertinent to an engineer when they are examining designs to see if they satisfy constraints, and the dial caliper allows people to do that.
Sidenote: Mr. Russell, I was having trouble with the picture software on my computer. Please excuse my lack of photographs; I will get them in as soon as I can.

Question #4: [I compared my measurements to Rohith Mandavalli]
a. Our measurements were not the same. The differences were usually less than 0.5 inches, with one notable exception (1.903 inch difference).
b. The measurements might differ because of human error, calibration mishaps in the dial caliper, or because of minute
differences in the form of each caliper.

Conclusion Questions
1. What additional tools may have helped to measure these parts?
2. Revisit Number 1. Measure at least five of the dimensions of your part using a standard ruler and record the measurements in brackets next to each caliper measurement. Which measuring device (the caliper or the ruler) provides the best measurements? Why?
