Measure the overall dimensions and the depth of the top opening. Be sure to measure the hole depth to the bottom of the hole, not the top of the plastic insert. Record the dimensions on the pictorial using appropriate significant digits.

Measure the location and size of the opening on the top of the part. Record your measurements on the top view below to the appropriate number of significant digits.

Using the dail calipers, carefully measure the depths and locations of the holes on the front and back faces of the part where the connector insert is located. Be sure to measure to the bottom of the holes, not the face of the plastic inserts. Record the measurements to the appropriate number of significant digits on the pictorial.

A fillet is an inside radius between two intersecting planes. A round is a rounded exterior blend between two surfaces. Use the dial caliper to estimate the radii of the outside rounds and the fillets at the corner of the holes. You will have to estimate the points of tangency (where the curve transitions into a straight edge). Assume that all the rounds have the same radius. Record the radii to the appropriate significant figures.
Estimated fillet radius: 0.2523 in
Estimated round radius: 0.4230 in
Estimated fillet radius: 0.2523 in
Estimated round radius: 0.4230 in

Using a dial caliper, measure and record the missing dimensions of the Automoblox wheel indicated in the view. Note that you do not need to measure the details of the rim pattern. Record the dimensions using appropriate significant digits. Important: There is a small circular rib on the inside cylindrical surface that fits around the axle pin. Measure the smallest inside diameter of that rib when recording the inside diameter of the wheel.

Measure and record the dimensions for the connector piece missing on the pictorial. Next to each dimension, list measurement type (outside diameter/part width, inside diameter/space width, hole/feature depth, and step distance) that you employed to measure the distance.
From left to right: inside space width, outside part width, step distance, step distance

Compare your measurements of the Passenger Section with a teammate who measured the same part.
a. Are your measurements identical to your teammates measurements? If no, describe the difference(s).
No, our measurements were not identical. There was a slight fluctuation on most of the measurements, but most within a hundreth of an inch.
b. Why would your measurements differ from those of another student who measured the same object?
Different people have different interpretations of numbers and of measurements.

Choose an object to measure. In your engineering notebook, sketch the object and record dimensions necessary to describe the object.

conclusion
1. What additional tools may have helped us to measure these parts?
A smaller caliper
2. Revisit number 1 above. 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?
The caliper provides better measurements because it measures with higher precision. With luck, the most precision you could get accurately with a ruler would be 1/64 of an inch.
