Unformatted text preview: 3 Exp#1: Using Uncertainties 4 Exp#1: Estimating the Volume of an Acrylic Block 1. 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 (its 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. 2. 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 vernier scale for the last digit....
