Intro to Engineering is my idea to have students applying the skills they have learned in their technology and math classes. This course is completely project driven with the hopes that each student work on long term project that is directly related to something they are passionate about. During the process students will engage in the design thinking process and use the engineering design process to take their ideas from conception to reality.
First year of engineering classes done in the Fab Lab
Popsicle stick bridge
Popsicle stick bridge
1) Materials permitted
a. All bridges must be made entirely of these materials:
i. Wooden Popsicle sticks (~11.5 cm long, ~1 cm wide, ~0.2cm thick).
ii. White all-purpose glue. Elmer’s or equivalent. No epoxy or Superglue.
iii. Wooden toothpicks (non-colored).
iv. Dental Floss
2) Specifications
a. The span under the bridge must be clear. The minimum unsupported clear span
must allow a 1000 mm long by 150 mm high box to pass freely underneath the
bridge span.
b. The maximum unsupported clear span cannot exceed 1200 mm.
c. The maximum length of the entire bridge must not exceed 1300 mm.
d. The maximum height of the bridge from the bottom of the abutments to the
tallest point shall not exceed 420 mm.
e. The maximum height of the deck or platform from the bottom of the abutments
shall not exceed 420 mm.
f. The maximum width of the bridge at any point shall not exceed 300 mm.
g. The minimum allowable width of the bridge abutments shall be 115 mm.
h. A smooth continuous deck for vehicular traffic must be provided along the entire
span of the bridge. The continuous deck must run the entire length of the bridge.
The continuous deck must be constructed entirely of Popsicle sticks. No solid glue
decks.
i. The load will be applied on the deck of the bridge. A clear opening of at least 100
mm by 200 mm must be maintained above the center of the bridge deck so the
loading jack may be applied at that center point of the deck.
j. The maximum bridge weight is limited to 13.23 pounds (6.0 kg) and the minimum
weight is 2.20 pounds (1.0 kg).
k. The bridge is considered to have failed once the maximum deflection of 50 mm is
reached or any member fails and the carried load at that point will become its
ultimate load.
Rube Goldberg Machines
Rube Goldberg Machines
Your job is to create a complicated machine that performs a simple basic task. Each machine must include at least 6 parts. You must have a spiral(screw), pendulum, gravity assist and rolling as part of your machine. Please be original. Do not copy a machine that has already been made and is online(we will search your model and idea and do not want to find it).
Spinning Top
Spinning Top
create a top in SketchUp that will spin for at least 1 minute. Be original in your design(you cannot create the standard design that is drawn on the board). You only get one print for this so make sure all print settings are proper for your model to spin a long time. Once your top is printing you can modify the top to help it spin longer. You can also build your top using any other method.
