Tech A says that serviceable wheel bearings can be repacked by removing the dust cap, filling it with grease, and reinstalling it. Tech B says that the cotter pin must be replaced with a new one every time it is removed. Who is correct?
Answers
Serviceable wheel bearings can be repacked by removing the dust cap and the cotter pin must be replaced with a new one every time it is removed. Therefore, both Tech A and B are correct.
Sealed bearing assemblies are typically prefilled with lubricant. They also make a more reliable and consistent installation process due to the fact that every into comes preset at the proper clearance.
Furthermore, the serviceable wheel bearings can be repacked by removing the dust cap, filling it with grease, and reinstalling it. Also, cotter pin must be replaced with a new one every time it is removed.

Why does the compression-refrigeration cycle have a high-pressure side and a low-pressure side?
a.The pressure difference is the result of polar molecular alignment due to the intense magnetic field created by the compressor motor.
b.So the refrigerant can condense at a low pressure and temperature and evaporate at a high pressure and temperature
c.The pressure difference isn't intentionally created but is simply the result of circulating refrigerant within the compressor.
d.So the refrigerant can evaporate at a low pressure and temperature and condense at a high pressure and temperature
Answers
Answer: D
Explanation:
The refrigerant can evaporate at low pressure and temperature and condense at high pressure and temperature. The correct option is D.
What is the Vapor compression cycle?The vapor compression cycle is a refrigeration cycle in which the heat is extracted from one place and is transferred to the atmosphere to cool the specified place.
Refrigeration is the process of keeping the temperature of the required place lower than that of the atmosphere by using different refrigeration processes like vapor compression, and vapor absorption processes.
In the vapor compression refrigeration cycle the refrigerant is evaporated at low pressure and temperature and condensed at high pressure and temperature.
The vapors of refrigerants are formed by taking the heat now these vapors are compressed in the compressor at a higher temperature and pressure than that of the atmosphere so that heat can be transferred to the atmosphere.

why is it important to follow the engineering design process before building a prototype
Answers
It is crucial to adhere to it since it provides a clear plan for how to identify the best solution to the issue in the most efficient manner.
You can experience your concept becoming real for the first time by creating a prototype. You can interact with, touch, and even destroy a prototype.
Why is it important to follow the engineering design process?Students that pursue careers in engineering and adhere to the steps of the design process are better able to think creatively because there is no one "correct answer." Through testing and ongoing improvement, engineers are encouraged to develop their own open-ended designs.
A working model of a solution is called a prototype. It is typically constructed using different materials than the final product, and it is typically less polished. A crucial stage in creating a final solution is creating a prototype, which enables the designer to test how the solution will function.
