Answer to Question #180138 in Mechanical Engineering for Harry

Question

Plan the experiments you will carry out, providing a list of other equipment you would theoretically need for the Laboratory Technician.

 

After you have written out a plan the experiments present your expected findings as a laboratory report listing equipment, method, results, calculations and conclusion. Your report should also include an evaluation of the two methods.

Answer 1

Following the described steps is indeed important for a good experiment. For example, we need to determine Young's modulus of a specimen. To do this, we need to have dimensions of the specimen to find its cross-sectional area A, its length L, we will need to measure its elongation under load F. The Young's modulus can be found a s

$$Y=\frac{\sigma}{\epsilon}=\frac{FL}{A\Delta L}.$$

For a good experiment, several data points will be needed.
