1. A torsion test shows that the shear modulus of an aluminum specimen is 4:60 x 10 psi. When the same specimen is used in a tensile test, the modulus of elasticity is found to be 12:2 x 10° psi. Find Poisson's ratio for the specimen. 2. An initially rectangular element of a material is deformed into the shape shown in the figure. Find e,y, E, and e, for the element. Deformed -Undeformed 16.6. 0.1992 mm 15.7 0.2 mm FIG. P2.37 1. A torsion test shows that the shear modulus of an aluminum specimen is 4:60 x 10 psi.
