Activity 3.3 Making Linear Measurements
1. Compare your measurements of the H plate with those of a teammate who measured
the same part.
a. Are your measurements identical to your teammate’s measurements?
no
b. If not, describe the difference(s).
none identical to my teammates. They were usually off by about 0.01 to 0.1 inches.
c. Why would your measurements differ from those of another student who measured
the same object?
No two dial calipers are the same and the measurements go into the thousandths. Even if the meas
2. As a group chose one of the following objects to measure. In your PLTW Engineering
Notebook, sketch the object and record dimensions necessary to completely describe
the object.
•
Graduated cylinder
•
Soda can
•
Coffee cup
•
White board marker
•
Another object as directed by your instructor
3. What additional tools may have helped to measure these parts?
Ruler
4. Return to procedure step 1 and 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.
a. Which measuring device (the caliper or the ruler) provides the best measurements?
the caliper
b. Why?
The caliper because the ruler only goes into hundredths at most while the caliper can continue into t
