10- Consider a cold worked (deformed) metal specimen that has a dislocation density of 1010 mm/mm2. Suppose that all the dislocations in 1000 mm (1 cm') were somehow removed and linked end to end. How far would this chain extend? A- 1 meter (10 km). B- 10 meter (10 km). 100 meter (10 km). 10 meter (10' km). 1010 meter (10 km). C- D- E-

Considering a finite cylinder of single crystal aluminum with a diameter (D) that has an axial unit screw dislocation at the center, what is the stress field around this dislocation in terms of D (diameter of cylinder) and r (radius which is the distance from dislocation center)

Sketch following modes of dislocation motion and name conditions that help them occur: 1. Cross slip 2. Climb up & climb down

Vanadium (V) has a BCC crystal structure. The atomic radius is R = 0.132 nm and the atomic mass is M = 50.94 g/mole. What is the density of Vanadium in g/mm3? Given: Avogadro’s Number NA = 0.6023 × 1024 (atoms/mole) Select one: a. 1.5 b. 0.021 c. 0.011 d. 0.0087 e. 0.00597

5- Question 5. Some hypothetical alloy is composed of 42.5 wt% of metal A and 57.5 wt% of metal B. If the densities of metals A and B are 4.35 and 6.27 g/cm3, respectively, whereas their respective atomic weights are 91.4 and 105.3 g/mol, determine whether the crystal structure for this alloy is simple cubic, face-centered cubic, or body-centered cubic. Assume a unit cell edge length of 0.395 nm.

Help me please

The flow stress for an alloy is 115 Mpa when its dislocation density is 10^6 cm^-2 and 207 Mpa when its dislocation density is 10^8 cm^-2. When the flow stress is 359 Mpa, Find the dislocation density.

You are given the density of a metal as 2.07 g/cm³. You are advised the crystallographic structure is fcc, and the atomic mass is 25.5 g/mol. What is the atomic radius of the metal? a. 0.15 nm b. 0.12 nm c. 0.11 nm d. 0.18 nm

The question is in the picture sent. I really do not understand what this question is even asking so a detailed explanation would be appreciated.
