Answer:
Solidification time is 2.78 min.
Explanation:
Chvorinov's rule states that the solidification time is directly proportional to the square of ratio of total volume to the total surface area of the cast.
Step1
Given:
Chvorinov's rule constant is 4 min/cm².
Length of the rectangular cast is 30 cm.
Width of the rectangular cast is 15 cm.
Thickness of the rectangular cast is 20 mm or 2 cm.
Calculation:
Step2
Volume of the cast is calculated as follows:
V = 900 cm³.
Step3
Total surface area is calculated as follows:
A=2(lb+bt+tl)
A=1080 cm².
Step4
Time of solidification is calculated as follows:
t = 2.78 min.
Thus, solidification time is 2.78 min.
Answer:
- It improves problem solving abilities and conceptualization
- Creates a competitive edge or approach to research problems
- It is vital for quality assurance and testing
Explanation:
When designing a solution to a problem, an engineer performs a research first in the area of problem. This will include understanding other works done by various individuals on similar topics. This shades light to the engineer on the concept of study and challenges him or her to think critically and develop a better solution concerning a problem. When the problem solving abilities are challenged, an engineer could come up with a better solution to a problem in terms of the technology applied and innovations to adjust to as a company thus putting the firm, products, customers and the entire economy at a better place than before in terms of problem solving approaches and solutions. Furthermore, research will offer a chance for quality control which is vital for success of a business in the production of products which meets or surpass users expectations.

Answer:
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. ... The term engineering is derived from the Latin ingenium, meaning "cleverness" and ingeniare, meaning "to contrive, devise".
