Final answer:
The minimum angle formed by the main hoop and main hoop braces can be determined by considering the geometry and symmetry of the hoop.
Step-by-step explanation:
The minimum angle formed by the main hoop and main hoop braces can be determined by considering the geometry and symmetry of the hoop.
If we define our coordinate system such that the origin is located at the center of the hoop, the integral should evaluate to zero.
