The Charpy V-notch (CVN) technique measures impact energy and is often used to determine whether or not a material experiences a ductile-to-brittle transition with decreasing temperature. Ten measurements of impact energy (J) on specimens of A238 steel cut at 60°C are as follows: 64.1, 64.7, 64.5, 64.6, 64.5, 64.3, 64.6, 64.8, 64.2, and 64.3. Assume that impact energy is normally distributed with o = 1J. Find the 95% Cl for u, the mean impact energy.a.

Evaluate the strain.
- A results below were recorded during tensile test for a steel specimen to be used to manufacture water reticulation steel pipes. The diameter of the specimen measured by an electronic vernier was found to be 0.597cm. Other measurements noted were the gauge length of 5.010cm,elongation 0.0635mm at load of 7.11kn, 7.33kn load at the yield point and 8.15kn load at the point of failure. The reduction of the cross-sectional at failure is estimated to be 35.06%.

- What is the difference in temperature tolerance between two specimens in Softening Point test? A. +2 °C В. +3 °C C. +1 °C D. +4 °CA three-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 6.7 mm; the specimen fractured at a load of 3190 N when the distance between support points was 46 mm. Another test is to be performed on a specimen of this same material, but one that has a square cross section of 16 mm in length on each edge. At what load would you expect this specimen to fracture if the support point separation is maintained at 46 mm? Ff = ____________ NQuestion: A structural component in the form of a wide plate is to be fabricated from a steel alloy that has a plane strain fracture toughness of 98.9 MPa sqrt(m) (90 ksi sqrt(in.)) and a yield strength of 860 MPa (125,000 psi). The flaw size resolution limit of the flaw detection apparatus is 3.0 mm (0.12 in.). If the design stress is one-half of the yield strength and the value of Y is 1.0, determine whether or not a critical flaw for this plate is subject to detection.
