INFORMATION ABOUT THE PRACTICALS ASSIGNMENTS.

Practical work is an essential part of work to be studied in Strength of Materials II. There would be expected of the student to hand in a report after each practical. In this document the student must have its preparation, results and conclusions. The document must be in the format and the same standard of work that you will give to your employer. This report must be handed in one week after completion of the practical for evaluation. The total mark for all your reports and practical tests is 35% of the course mark. An average of 50% for the practical mark must be obtain for admission to the main evaluation
NB: You can be refuse entrance to the laboratory if: o o You did not prepare. You did not have your white coat and laboratory notes.
