Answer:
Explanation:
Given that
Unit cell is in FCC
Here given direction is not clear visible so we take direction [001].
We know that linear density(LD) given as
![LD=\dfrac{Number\ of\ atoms\ in\ the\ direction\ vector}{d_{[001]}}](https://tex.z-dn.net/?f=LD%3D%5Cdfrac%7BNumber%5C%20of%5C%20atoms%5C%20in%5C%20the%5C%20direction%5C%20vector%7D%7Bd_%7B%5B001%5D%7D%7D)
So the number of atom will be 1/2 in direction [001]
In FCC
Answer:
stress = 8,556 Psi. or (stress = 59 Mpa)
Explanation:
stress = force / area
force P = 3 tons (convert to lbs. for units consistency)
1 ton = 2240 lbs.
P = 6,720 lbs.
steel bar Diameter D = 1 in. (convert to d
Area of steel bar = (π * 1²) / 4 = 0.785 in²
therefore, stress = 6720 lbs. / 0.785 in²
stress = 8,556 Psi.
in Mpa ----- 8556 Psi * 0.00689476 MPa/Psi = 59 Mpa
Answer: Technician A
Explanation: A coolant recovery system Is one of the most important part of a vehicles cooling system. When a coolant gets too hot, it forces it way out of the spring loaded radiator cap so as to relieve pressure. Any coolant which has escaped is recovered back through the discharge tube located in the recovery tank. The system is usually air free
