Answer:
According to the Principles of Project management, the three factors which dominate the lifecycle of any project are:
- Time;
- Cost; and
- Performance.
The relationship between the three is usually governed by trade-offs.
Explanation:
In simple term, in executing a project, one must deal with the factors mentioned above.
It is always desirous for a project to be finished within a stipulated time. If the time required is reduced inconsiderably, it will most likely incur more cost and even impact performance.
On the other hand, if the project is cost-sensitive and is executed to a very minimalistic budget, performance will be impacted and it may take a protracted amount of time.
In addition to the above, if the principal decides to change the original design of the project, the performance expected is altered. This will attract additional time as well as cost.
It is possible for any of the above factors to be renegotiated and readjusted at any time during the project. It usually is a trade-off.. that is one for the other.
Cheers!
Answer:
Time for solidification of the casting is 186 sec.
Explanation:
Chvorinov's rule is used to find the solidification time for any casting shape.
Step1
Given:
Diameter of the disk is 650 mm.
Thickness of the disk is 16 mm.
Chvorinov's rule constant is 3.2 sec/mm².
Step2
Calculation:
Total volume of the disk is calculated as follows:


V= 5309291.585 mm³.
Step3
Total surface area of the disk is calculated as follows:


A= 696334.0117 mm².
Step4
Chvorinov's rule for time calculation is expressed as follows:



t=186 sec.
Thus, the time for solidification of the casting is 186 sec.
Answer:
somewhere around 34.2223 meters thick but that's what I am estimating.
