2.1 C1: THE USES OF BASIC INSTRUMENTS Procedure:
You
balar
You are given a meter stick, a Vernier calipers, a micrometer Screw gage, and a spherometer to measure
the followings: length, breadth, thickness, radius, depth of curvatures and etc. of materials provided by
your laboratory instructor. Use the data obtained to calculate the following:
