Stress (MPa) 2000 Using the stress-strain results shown in the figure, determine the 0.2% offset yield strength and the strain at the onset of necking. Indicate both on the graph and write the value along with units in the space provided.

For P = 100 MPa, determine the range of values of τxy for which the maximum tensile stress is equal to or less than 60 MPa. (Round the final answer to one decimal place.)

A thin rectangular plate ABCD is deformed into a parallelogram as shown in the figure below.  The width of the plate is w = 1300 mm, and the height of the plate is h = 1700 mm.   The shear strain at A is known to be +4172 μrad.  Assume a = 2.9 mm.  Calculate the magnitude of dimension b in the figure.

An aluminium specimen with an initial gauge diameter d, = 10 mm and gauge length, 1, = 100 mm is %3D subjected to tension test. A tensile force P= 50 kN is applied at the ends of the specimen as shown, resulting in an elongation of 1 mm in gauge length. The Poisson's ratio (µ) of the specimen is Take shear modulus of material, G = 25 GPa. Consider engineering stress-strain conditions. P
