Answer:
thrust washer
can be used to eliminate rubbing friction of wheel touching frame
Answer:
In the acid processes, deoxidation can take place in the furnaces, leaving a reasonable time for the inclusions to rise into the sla*g and so be removed before casting. Whereas in the basic furnaces, deoxidation is rarely carried out in the presence of the sla*g, otherwise phosphorus would return to the metal.
Handsaw teeth are very sharp: to avoid being cut by the teeth, keep hands and fingers well away from the
path of the blade
Answer:
The ability to read electrical schematics is a really useful skill to have. To start developing your schematic reading abilities, it's important to memorize the most common schematic symbols. ... You should also be able to get a rough idea of how the circuit works, just by looking at the schematic.
Explanation:
Answer:
t = 1456.8 sec
Explanation:
given data:
contant k = 2.60*10^{-6}
rate of crystallization is 0.0013 s-1
rate of transformation is given by
use specifies value to solve 
it is ime required for 50% tranformation
Avrami equation is given by
n = 1.88
second degree of recrystalization may be determine by rearranging original avrami equation
![t = [\frac{-ln(1-y)}{k}]^{1/n}](https://tex.z-dn.net/?f=t%20%3D%20%5B%5Cfrac%7B-ln%281-y%29%7D%7Bk%7D%5D%5E%7B1%2Fn%7D)
for 90%completion
![t = [\frac{-ln(1-0.9)}{2.60*10^{-6}}]^{1/1.88}](https://tex.z-dn.net/?f=t%20%3D%20%5B%5Cfrac%7B-ln%281-0.9%29%7D%7B2.60%2A10%5E%7B-6%7D%7D%5D%5E%7B1%2F1.88%7D)
t = 1456.8 sec
