Intro to Measurement Uncertainty 2011
Measurement Uncertainty and Significant Figures There is no such thing as a perfect measurement. Even doing something as simple as measuring the length of a pencil with a ruler is subject to limitations that can affect how close your measurement is to its true value. For example, you need to consider the clarity and accuracy of the scale on the ruler. What is the smallest subdivision of the ruler scale? How thick are the black lines that indicate centimeters and millimeters? Such ideas are important in understanding the limitations of use of a ruler, just as with any measuring device. The degree to which a measured quantity compares to the true value of the measurement describes the accuracy of the measurement. Most measuring instruments you will use in physics lab are quite accurate when used properly. However, even when an instrument is used properly, it is quite normal for different people to get slightly different values when measuring the same quantity. When using a ruler, perception of when an object is best lined up against the ruler scale may vary from person to person. Sometimes a measurement must be taken under less than ideal conditions, such as at an awkward angle or against a rough surface. As a result, if the measurement is repeated by different people (or even by the same person) the measured value can vary slightly. The degree to which repeated measurements of the same quantity differ describes the precision of the measurement. Because of limitations both in the accuracy and precision of measurements, you can never expect to be able to make an exact measurement. -

Measurements
Measurements INTRODUCTION Physics is a quantitative, experimental science that relies heavily on the ability to perform accurate, precise measurements. In this experiment, the basic techniques for making measurements and for analyzing data will be introduced. The physical characteristics of length, mass, volume, and density will be measured. THEORY In measuring physical quantities, it is important to use the proper measuring instruments. Often the degree of precision desired for a particular measurement determines the type of equipment that should be used. For measuring linear dimensions such as length, width, or height, there are two types of common instruments available: the straight-edged ruler and the caliper. The caliper consists of two jaws, one fixed and one movable, used to determine the distances between two surfaces or to measure the diameters of small objects. Note: The measurement error associated with each device is normally about half of the smallest dimension that the instrument is capable of measuring. The Digital Caliper Figure 1: Digital caliper The digital caliper consists of one fixed jaw, attached to a main beam, and one movable jaw that slides along the main beam. The instrument that we will be using in lab for these measurements can be set to readout in either English or metric units. The distance between the two measurement jaws is displayed on the LED digital readout display located on the slider. When measuring a linear dimension using the digital caliper, the workpiece is placed between the jaws, as close as possible to the main beam, and the jaws are closed making contact with the workpiece. -

PUNCHES and CHISELS Punches and Chisels the Anvil End on Heads of Snap-On® Punches and Chisels Are Machined to a Modified Parabolic Curve
PUNCHES AND CHISELS Punches and Chisels The anvil end on heads of Snap-on® punches and chisels are machined to a modified parabolic curve. This design directs the striking force to the center of the tool head to allow slow metal displacement. The parabolic curve controls mushrooming to reduce chipping and splitting. Heads should be re-dressed to their original shape with hand files as necessary. The tough steel alloy is machined and differentially heat treated for optimum performance. The hardness of the striking head is reduced to help toughness and add qualities that result in a slower mushrooming of the striking surface. PPC250BK Punch and Chisel Set.

Measurements Purpose Equipment Discussion
rev 05/2019 Measurements Purpose To learn the proper use of a meterstick, vernier caliper, micrometer, and electronic scale, and to learn how to use the correct number of significant figures in data and results. Equipment Meterstick, 2-meterstick, vernier caliper, micrometer, laboratory balance, ruler, metal cylinder. Discussion The number of significant figures in a measurement depends on the measuring device and its precision. When an object is measured in a same manner, a vernier caliper has a greater precision than a meterstick and a micrometer has a greater precision than a vernier caliper. A measurement reading should have one more significant figure than the smallest subdivision marked on the scale. 2 (Main scale) 3 0 (Vernier scale) Alignment at 7 2.1 cm + 0.070 cm = 2.170 cm (main scale at vernier 0 mark) (vernier scale) Vernier Caliper. Example of reading: The main scale gives a reading to 1/10 of cm at the 0 mark on the vernier scale. The next digit (the second decimal place in cm) is made on the vernier scale where the marks line up. If a mark on the vernier scale is aligned with a mark on the main scale as in the first example, the mark on the vernier scale gives the next digit and the estimated figure is 0. 1 2 (Main scale) 3 0 (Vernier scale) No alignment. Phase change for 2 and 3 marks. 2.0 cm + 0.025 cm = 2.025 cm (main scale at vernier 0 mark) (vernier scale) Example 2: If no marks are aligned, there is a phase change between marks.
