Measurements Lab 0.1 INTRODUCTION In this lab, you will determine the experimental values of the surface area and volume of a slotted brass weight. You will also obtain the experimental value of the density of brass, and compare to its accepted value. You may assume the cross-sectional area of your weight has a shape as shown in the Fgure below: 6 ? I R d Also remember that the volume of a cylinder is given by π · R 2 · h and the surface area by 2 · π · R 2 +2 · π · R · h . 6 ? s h R 0.2 EQUIPMENT AVAILABLE Vernier caliper, micrometer, meter stick, scale, and slotted brass weight (marked 50g, 100g, and 200g). 1
0.3 PROCEDURE Weigh the slotted weight. Report the measured mass, m meas ; Use a vernier caliper 1 to measure R and d . Use the micrometer 2 to measure h . Using the symbolic math toolbox of MATLAB, obtain the experimental volume and experimental surface area. See section 0.5 below for help; Calculate the density of brass, ρ exp ;
