(2) You are tasked with testing a new alloy. Previous tensile testing revealed the alloy's Young's modulus to be 127 GPa. The tensile test specimen, which had an initial 15mm diameter, was stressed elastically in tension. It was found that a force of 20kN caused the diameter of the sample to experience a 4.9um reduction. a. Determine the Poisson's ratio of the material b. Determine the change in diameter which would result from a 15kN loading

Two 40 ft long wires made of different materials are supported from the ceiling of a testing laboratory. Wire (1) is made of material H and has a diameter of 3/8 in. Wire (2) is made of material K and has a diameter of 3/16 in. When a load of 225 lb is applied to its lower end, wire (1) stretches 0.10 in. When the same 225 lb load is applied to the lower end of wire (2), wire (2)...

1. A single crystal sample of a metal with a HCP structure is subjected to an axial tensile force. The sample is of circular cross-section, with a diameter of 4 mm, and is of 50 mm length. An elastic extension of 0.047 mm is measured when an axial tensile force of 1.25 kN is applied. When the tensile force is increased to 2.8 kN plastic deformation commences. (a) Given that Poisson’s ratio for the metal is 0.35, estimate the theoretical...
