# Goal

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.
• Ideas
