LAB WORK VL1 PRECISION INSTRUMENTS: VERNIER CALIPER AND MICROMETER Objective To use a metric Vernier caliper to obtain the dimensions of various objects. To calculate the volume of a cylinder, sphere and a block using the dimensions obtained with the Vernier caliper. To use a metric micrometer (screw gauge) to obtain the dimensions of various objects. To calculate the volume of a sphere and a wire using the dimensions obtained with the micrometer. Fundamental Principle: The Vernier caliper was introduced in 1631 by Pierre Vernier. It utilizes two graduated scales: a main scale similar to that of a ruler and a specially graduated auxiliary scale, the Vernier, which slides parallel to the main scale and enables readings to be made to a fraction of a division on the STUDENT NAME: Marcellino Said CLASS: Physics 116 D003 18045 DATE: 9/21/2020 INSTRUCTOR: George Poppe DATA TABLE - LAB WORK VL1 | 1
PRECISION INSTRUMENTS: VERNIER CALIPER & MICROMETER main scale. With this device you can take inside, outside, and depth measurements. The micrometer or screw gauge was invented by William Gascoigne in the 17th century, and is typically used to measure very small thicknesses (e.g. foil, paper) and diameters (e.g. wires, strand of hair, spheres). It consists of a screw of 0.5mm, a main scale and another scale engraved around a thimble which rotates with the screw and moves along the scale on the barrel. The
