22-Mec-B4 Integrated Manufacturing Systems: December 2019

Paper format. National Examinations, December 2019 — 16-Mec-B4 Integrated Manufacturing Systems. Three hours, OPEN BOOK, any non-communicating calculator permitted. Seven questions are printed and any five constitute a complete paper; all questions are of equal value, so each is worth 20 marks of the 100 available. Note 1 of the paper invites the candidate to state any assumption made where a question is open to interpretation, and this solution uses that licence wherever the source withholds a datum. Every one of the seven questions is worked below, because the set is a study resource rather than a three-hour sitting.
