Answer: preventive maintenance
Explanation:
Answer:
Both of them are wrong
Explanation:
The two technicians have given the wrong information about the wires.
This is because firstly, a higher rating of AWG means it is smaller in diameter. Thus, the diameter of a 18 AWG wire is smaller than that of a 12 AWG wire and that makes the assertion of the technician wrong.
Also, the higher the resistance, the smaller the cross sectional area meaning the smaller the diameter. A wire with bigger cross sectional area will have a smaller resistance
So this practically makes the second technician wrong too
Answer:
4.5kg/min
Explanation:
Given parameters
if we take
The mass flow rate of the second stream = 
The mass flow rate of mixed exit stream = 
Now from mass conservation
The temperature of the mixed exit stream given as
Therefore the mass flow rate of second stream will be 4.5 kg/min.
Technician B is correct because the way aluminum collapses can be predicted.
Hardened steel and aluminum are two metals used for different purposes including:
- Construction.
- Appliances.
- Small utensils.
- Airplanes.
- Vehicles.
These two materials have slightly different features in terms of resistance, flexibility, etc.
In the case of hardened steel, this is considered to be malleable but strong. This means it is possible to change its shape under some conditions but it can resist great forces and pressure. Moreover, if the hardening process is carried out properly all the areas should be equally strong.
On the other hand, aluminum is recognized due to its durability and for being lighter than other materials. Despite this, aluminum is more flexible than steel and collapses under weaker forces. This has been widely studied because aluminum collapse shows a predictable pattern.
Based on this, only technician B is correct.
