Ground Clearance is used to describe the maximum height of an obstacle the automobile can driver over without scratching the underneath (Figure below).
Another problem with cars is that they may not be able clear a ramp if the ramp has too much inclination with respect to the ground level. The front bumper may collide with the ramp before the front wheels can maintain contact with the ground and the ramp.
Is there a specific term for this value (theta in the figure above)?
To give a bit of context, the parking lot near where I live has a ramp that constantly scratches the bottom of my car's front bumper, and I am looking for ways to avoid it.
