Unformatted text preview: l f . The true strain ε f at fracture is 0.912. If the initial diameter d is 12.7 mm, calculate the diameter at fracture d f . Q8. A test specimen with a gage length of 50 mm and an area of 200 mm 2 is used in a tensile test. During the test, the specimen yields under a load of 98,000 N. The corresponding gage length is 50.23 mm. This is the 0.2 percent yield point. The maximum load of 168,000 N is reached at a gage length of 64.2 mm. Determine the (1) yield strength, (2) modulus of elasticity, and (3) tensile strength. Q9. In Question 8, fracture occurs at a gage length of 67.3 mm. (1) Determine the percent elongation. (2) Determine the percent reduction in area if the specimen necked to an area of 92 mm 2 . Q10. The figure below illustrates the phase diagram of two components with no solid solubility. (1) What is the name of the composition at point C? (2) Describe its characteristics....
