ENGIN 45 Study Guide - Midterm Guide: Tensile Testing, Bravais Lattice, Chemical Formula
Document Summary
The mechanical properties of materials are described in engineering terms using simple concepts and normalized parameters. Choose the best answers from those presented below for 2 points each: the data at right could have been obtained from a uniaxial tensile test three-point bend test. Brinell hardness test: this data reveals that the sample had a yield strength of. 0. 06: necking would have been observed in this sample when the stress reached. 450 mpa: dislocations began to move in this sample when the strain exceeded. 0. 0075: the construction at right represents percent elongation to failure estimate of toughness modulus of elasticity. A lattice is an array of points in space with identical environment. Identify the lattice directions and lattice planes shown in the sketches below for 3 points each. Note especially the scale markings and use them to precisely identify any fractional intercepts.
