Unit 2 – Mechanical Systems
Major Lab
Introduction
As you have discovered in this unit, simple and complex machines are
everywhere and help us in various ways. Studying mechanical advantage allows us to
understand how we can use simple machines and help us develop new applications.
We can apply the principles of mechanical advantage in many aspects of our daily lives.
Assignment
In order to demonstrate your understanding of concepts in this unit, you will be
required to design and conduct an experiment to investigate how mechanical advantage
applies to typical daily events at St. Edmund Campion SS. You will present your
findings to the class in an organized, engaging presentation.
Your presentation will be a maximum of 5 minutes and must include a
demonstration of your chosen application. Each student in the class must have a
different application.
You will receive class time to collect your data and organize your presentations,
but you will need to ensure that you are prepared so that you use the time effectively.
Your presentation should include:
 A clear description of the physical event/device, including identifying the relevant
simple machine(s)
 A demonstration of how you collected your data
 An explanation of how mechanical advantage is used to accomplish a task or
make it easier
 A figure, table, or graphical representation of your data
 A description of how technologies have been developed to increase efficiency or
improve the use of the technology
 An organized list of academic references
Your presentation will be assessed using the rating scales provided. Be sure to follow
all conventions discussed in class.
REMEMBER:
 Your presentation should be engaging and appropriate for your audience
 You may assume that your audience has a basic understanding of topics
covered during this unit
 Choose a topic that you can easily and safely demonstrate in class
