Tension specimens (diameter d0 0.500 in., gage length L0 2.00 in.) made of structural materials A and B are tested to failure in tension. (a) At failure the distances between the gage marks are LAf 2.90 in. and LBf 2.22 in.; the corresponding diameters at the failure cross sections are dAf 0.263 in. and dBf 0.471 in., respectively. Determine the percent elongation in 2 in. and the percent reduction in area for these two materials, and classify each material as either brittle or ductile. (b) From these tensile tests the following data are also obtained: EA 10.0 103 ksi, (Y)A 5 ksi, (U)A 13 ksi; EB 10.4 103 ksi, (Y)B 73 ksi, (U)B 83 ksi. From the data given here, make rough sketches (to scale) of the stress-strain diagrams of materials A and B.

A test is set-up as shown in the figure below. A cylindrical mold 4" in diameter is filled with silt to a height H1 = 0.20 ft whose coefficient of permeability is 6.10 x 10^-4 ft/min.A second coaxial mold, placed on top of the silt inside the first mold, has an inside diameter of 1.50" and height of H2=0.30 ft. Its thickness is negligible. The inside of this second mold is filled with the same silt, but the annular ring outside is filled with sand whose coefficient of permeability is 2.50 x 10^-3 ft/min.The test set-up is a permeameter of constant head. Water is placed in the mold and maintained at a level h=1.25 ft above the level of the outlet. It may be considered that the system consists of a fictitious soil of thickness H = H1 + H2 and coefficient of permeability kf.What is the total amount of flow that percolated after 30 minutes?
