If: y = x2-x-12 Then points of contact are at: (0, -12), (4, 0) and (-3, 0)
This test measures the smallest distance at which two points of contact can be felt.
Compared to a 3-legged stool it would. Consider the 3 or 4 points where the bottom of the legs make contact with the floor (which need not be even). Any three points are always in one plane so all points of contact for a 3-legged stool will always lie in the plane, thereby preventing rocking. Four points need not be coplanar and if they are not, the stool will rock.
Yes. One can satisfy oneself that this is true just by considering the symmetry of the construction.
Instantaneously, the points of contact between the tyres and the road.
