Question

Why was the top of the rectangular cut chosen as the sketching plane for the circular cut through the second cut feature (the small hole through the top of the part) instead of the top of the part?

a) Minimizes material removal
b) Aligns with the center of mass
c) Aesthetically pleasing design
d) Provides structural stability

Answer 1

The top of the rectangular cut was chosen as the sketching plane for the circular cut through the second cut feature because it aligns with the center of mass of the object and provides structural stability.

Step-by-step explanation:

The top of the rectangular cut was chosen as the sketching plane for the circular cut through the second cut feature (the small hole through the top of the part) because it aligns with the center of mass of the object. The location of the center of mass determines the object's rotational inertia and contributes to its angular momentum. By aligning the circular cut with the top of the rectangular cut, the center of mass remains in the same position, providing structural stability.
