5. (More on the wheel o) Using the notation of Exercise 4, assume that 1/1, but try to find a solution where one of the 's is zero In particular, suppose the segments are ordered in such a way that papir, for all i=1,2, n. Then segment is the "worst" segment

(a) Find a solution with a 0 and all other a's positive.

(b) Evaluate this solution for the wheel of Example 15.5
