MAKE AN EXECUTIVE SUMMARY

In industry, the executive summary maybe the most important part of the report. The decision to read your report beyond this page may be based on how well you have stated your case. The executive summary may also satisfy the reader that enough information has been provided to make a decision or understand the concepts without reading the entire report.

Briefly state the purpose of the experiment.

Summarize the main results

Give the main conclusion(s).

Experiment 4 Purpose: Determine and compare the tensile properties of Acrylic, Nylon, and Polycarbonate (Lexan) samples. Compare materials in terms of: Youngs modulus, elastic limit, yield, ultimate tensile strength, shape of the curve. Lab Experiments

Tensile testing: What is tensile testing? What is it used for? How does it work? Perhaps the most used test of a materials' mechanical properties is the tensile test. A flat strip or cylindrical piece of the material, having length L and cross- sectional area A, is anchored at one end and subjected to a load P acting on the specimens longitudinal axis at the other end.
