The apparatus used for the determination of Young's modulus in the elementary laboratory at Drake has been the vertical suspended wire type, in which the sample under test is loaded and readings taken directly by means of a vernier attached to the wire. Although the readings are accurate to one one-hundredth of a centimeter, the scale cannot be conveniently read, the measurement of the length of the wire necessitates the use of a ladder, and the heavy weights are not easily handled. It is hoped that this new instrument will facilitate the experiment, although it is recognized that the weight of the wire, and friction in the bearings and gauge, may introduce slight errors.
