A steel alloy specimen having a rectangular cross section of dimensions 19.1 mm × 3.0 mm (0.7520 in. × 0.1181 in.) has the stress-strain behavior shown in the Animated Figure 6.22. If this specimen is subjected to a tensile force of 95120 N (21380 lbf) then (a) Determine the amount of elastic strain induced. (b) Determine the amount of plastic strain induced. (c) If its original length is 590 mm, what will be its final length after this force is applied and then released? The elastic modulus for steel is 207 GPa.

A cylindrical specimen of some metal alloy 8.6 mm in diameter is
stressed in tension. A force of 9070 N produces an elastic
reduction in specimen diameter of 0.0048 mm. Calculate the elastic
modulus (in GPa) of this material if its Poisson's ratio is
0.33.

A direct shear test is conducted on a large specimen of dry sand
(square cross section with following dimensions: 7.5 cm x 7.5 cm x
3.0 cm [height], Mass = 271.0 g) with a normal stress of 500 kPa.
Failure occurred when the horizontal force was 1.96 kN. For the
same sand, tests were also conducted to determine the specific
gravity and the maximum and minimum void ratios. These tests
yielded the following results: Gs= 2.65, emax=0.80, emin = 0.45....

21 Gpa, Es = 210 GPa, and free shrinkage strain = 0.0004, estimate
the force carried by concrete and steel after shrinkage. If
concrete tensile strength, ft = 5 MPa, will crack develop in this
specimen?

sides of lengths a and b. One face of the pipe is maintained at a
constant potential V = V0 while the other 3 faces are grounded (V =
0). Using separation of variables, find the potential for points
inside the pipe V (x,y).
