Paper format. 16-Mec-B9 Advanced Engineering Structures, National Examinations, December 2019. Three hours, open book, any non-communicating calculator permitted. Seven problems of equal value; any five constitute a complete paper. All seven are solved here, because the set is a study resource rather than an examination script.
