1. A material exhibits linear elastic behavior up to a stress of 200 MPa and a
strain of 0.00125. What is its Young’s modulus?
ANSWER E = σ/ε = 200 MPa / 0.00125 = 160 GPa
2. A bronze alloy specimen having a diameter of 12.8 mm and a gage length of
50 mm was tested to fracture. Stress and strain data obtained during the
test are shown. Determine the Young's modulus. - ANSWER 14000 MPa
3. What is necking, and when does it occur during a tensile test?
ANSWER A localized reduction in cross-section that starts after the
ultimate tensile strength is reached.
4. A tensile test specimen of 1045 hot-rolled steel having a diameter of 0.505
in. and a gage length of 2.00 in. was tested to fracture. Stress and strain
data obtained during the test are shown. Determine the Young's
modulus.(look at graph in canvas) - ANSWER 7900 ksi
