The cartilaginous disc you are referring to is the pubic symphysis. It is a fibrocartilaginous joint between the two pubic bones, allowing them to move independently during childbirth. Relaxin hormone released during pregnancy softens the ligaments around the pubic symphysis, allowing it to expand slightly to accommodate the growing fetus and facilitate childbirth.

How do the cartilaginous rings of trachea looks like?
They are C-shaped, with the opening in the back so that when you swallow food, the esophagus expands into the area of the trachea to allow the food (called a bolus) to go down. This process is called deglutition. If they were not C-shaped and positioned this way, your food would not be able to go down into your stomach.
What happens to a particle of a substance when it expands?
individual particles do not expand, when a substance expands it is the dead space between the particles that expands and the particles begin to move around (assuming the substance was solid to begin with). If a particle did expand it would loose cohesion and break apart (possibly creating an atomic reaction depending on how it was expanded)
