Abstract

Figure 1 illustrates the apparatus for shear-modulus measurements. The specimen to be tested is secured to two concentric stainless steel cylinders. One of the specimen ends is inserted into a brass adapter which screws into a brass fitting soldered to a cylinder 8½ in. long and 2 in. in diameter with 0.1-in. wall thickness. The other end is secured to a small adapter which also screws into a brass fitting soldered to a cylinder 61/8 in. long, of 1½ in. diam, and 0,07 in. in wall thickness. Figure 2 illustrates how each end of the specimen is attached to an adapter. The outer cylinder Is soldered to a stationary brass plate which rests on a one-liter glass dewar. A couple is applied to the inner cylinder by means of slotted brass weights placed on pans. This vertical force is transformed to a horizontal force through a set of pulleys attached to the brass plate. The weight pans are held up with constantan wires which are attached to slots soldered to brass sectors.
