Calculate the final volume (in cm3) of a 40 cm long cylindirical copper rod with a cross-sectional area of 1.2 cm2 when it is
a) stretched with a load of 4.0×105 Newtons,
(ν= 0.32, E= 70 GPa, σy = 300 GPa, σTS= 650 GPa, rCu = 120 pm)
b) Compare the absolute volume change during this process.
c) Assume that the stress is applied along [100] direction. Compute the unit cell parameters (a, b,
and c) during the application of the stress.
2) A cylindirical rod of a length of 22.4 cm and a radius of 1.2 cm is deformed plastically when it is pressed
with load of 4.758×108 Newtons. Calculate the final volume of the specimen after the load is released.
(ν= 0.32, E= 70 GPa, σy = 300 GPa, σTS= 650 GPa.)

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
