QUESTION 2: (4 pts) A gear assembly as shown below calls for a tolerance o the dimension of the " Lgap ". Assume the gear sections LA,LB,LC,LD, and LE are all independent with dimension values of 4006.0(mm),2006.0(mm),2206.0(mm),2006.0(mm), and 1806.0(mm) respectively. The total length, L, is specified to be 150012.0(mm). What is the expected dimension and tolerance on " Lgap "? In addition, the customer's specification on this "Lgap" is given as 3009.0(mm). (Hint: Use the statistical tolerancing, RSS approach; and assume all dimension tolerance for L,LA,LB, LC,LD, and LE and Lgap are calculated based on 6 )
