Welcome to the official website for the EA2 Hangout with Hands-on Mechanics, the place for information and updates as the quarter progresses.
Updates
- We are making a small adjustment to how we are going to run the tests. We are going to insert the tool while the bed is fluidized to make sure each team’s design survives the penetration stage, and to make sure everyone has a crack at the prizes. Competing teams have the assurance of experts in soil-machine interaction that this will not effect the “steady state” performance as designs are pushed laterally.
- Test days were postponed to February 18 and February 19. Good luck!
- We are on Slack: ea2hands-onmodule.slack.com! Watch your inbox for an invitation (if you signed up through the link below), or directly contact Victor (victorlimontitla2021@u.northwestern.edu) to join.

Attendance of these meetings is not required to participate in the design competitions, and you can come to the meetings just to hangout and eat pizza. One way or another, please complete this sign-up form so we know who you are and how to contact you:
About the EA2 Hangout
We are running this new, totally optional activity in the Winter Quarter of the 2019-2020 academic year to support and enhance the freshmen engineering course Engineering Analysis 2 through informal discussions and hands-on activities. Students enrolled in the course can attend the EA2 Hangout to work individually or in teams to design, build, and test prototypes in two different design competitions. The idea is to eat pizza, make friends, share EA2 tips, and even win some prizes, with a total of $600 in prizes up for grabs!
We will have two different design competitions, each of which integrates with concurrent course content:
- A simple earth manipulator to be tested in the Soil-Machine Interaction Laboratory
- A 3D-printed truss to be tested to failure in the Civil and Environmental Engineering undergraduate labs
We are meeting at two different times each week throughout the quarter:
- Tuesday, 5:00-6:00pm, Tech M345
- Wednesday, 5:00-6:00pm, Tech M345
