Design a brief lab session and write the lab manual. You will A written document (pdf) in the form of a lab manual: no more than 4 pages.
What to do:
Think of a physical variable/material property that is typically measured in mechanical engineering and design a brief laboratory session that shows how to conduct measurement(s) for such variable.
IMPORTANT: you cannot choose a physical variable that can be directly measured with an instrument. It has to be an indirect measurement. For example, you cannot choose mass as the physical variable since a scale can directly provide that measurement. Instead you could choose density and measure mass and volume in order to find density.
Once you pick a physical variable/material property you will:
Choose real measuring devices/instruments/sensors to carry out the measurement you picked.
Explain how the measuring devices/instruments/sensors work.
Describe in detail step by step how to use the measuring devices/instruments/sensors to eventually obtain the desired measurement.
Written document structure
The written document you submit should have the following sections:
- Introduction: goal of the lab session and context for the measurement. Relate it to real applications. Where does this measurement occur? What is it used for? Why is it important?
- Theory: here you will present the measuring devices/instruments/sensors needed to conduct your measurement and the fundamental principles behind such devices. Choose real existing measuring devices/instruments/sensors and provide the manufacturer/seller and model numbers. Also, include any equations required for your measurement and explain them briefly and clearly.
- Procedure: explain in full detail, step by step, how to use the measuring devices/instruments/sensors to conduct your measurement. Use a bulleted list for the procedure.
- Uncertainty: list the sources of uncertainty for the measuring devices/instruments/sensors you decided to use.
