Exp#1:
Estimating The Volume Of An Acrylic Block
Overview
This lab is a simple exercise in measurement principles, combined with a first practice in uncertainty
analysis.
An acrylic block has been machined using a laser cutter, driven by a solid modeling
program, to produce a rectangular parallelepiped (it’s actually a cuboid) with a cylindrical cutout in
the center.
The basic idea is to measure the volume of the object through careful use of the available
instrumentation, taking enough measurements so that a measurement uncertainty can be calculated.
Estimate the volume of the object, and compare it with the prescribed volume calculated from the
solid modeling program.
Make a simple statement about whether the estimates are the same, or
different.
Procedure
1.
Work out how to use the digital caliper and the micrometer.
The latter requires the reading of a
vernier scale for the last digit. If you get lost, then see if you can work it out from scratch, starting
with an object of zero length.
