On the surface of a certain component made of aluminium with a
modulus of elasticity of 75 GPa and a Poisson’s ratio of 0.35, a
strain gauge rosette measures the following strains 0 = –94 × 10-6
60 = 370 × 10-6 120 = 235 × 10-6 The aluminium has a yield strength
of 95 MPa. a) Determine the strain components x, y, and xy from the
strain gauge measurements. b) Determine values for x, y and xy from
the...
