ANGLIA RUSKIN UNIVERSITY
Department of Engineering and the Built Environment
MOD005250 Engineering Science and Materials
This is assignment is to be submitted to the Turnitin on or before 14:00 on the 4th May 2018.
Laboratory reports
You will carry out four laboratory procedures:
Density of materials
Compressive strength of concrete
Tensile strength of metals and Young’s modulus
Vectors and Couples
The assignment consists of writing these up in a technical report format. Each report will include:
Introduction.
o Objectives of the experimental procedure are described.
o Brief description of the testing method, use sketches and diagrams as much as possible.
Presentation of results and related calculations
Conclusions
o Discussion of results
o Limitations and assumptions
o Comparison with published data where necessary
