Truss Design Challenge Experiment - Group 2

Experiment Description
For this experiment, the students in the lab were required to design a truss or bridge to span a specific distance and resist a 100 lb load in a four point flexure test. All the requirements for the bridge are shown below:
• Span length of 400 mm
• Width of 75 mm
• Maximum height of 75 mm
• Maximum weight 100 grams
• Must hold 45 kg (100 lbs)
• No adhesion (glue, etc..) for connections

The challenge for the student in this experiment was their bridge had to be printed in separate parts because the bridges were to large to print all at once. The students had to design connections for these parts without the use of glue or other adhesives. The connection design was critical because that is the weakest points on their trusses.

Information on Group 2’s Bridge:
This is the design from Group 2 in the laboratory. Their truss design is commonly known as a Howe Truss. This group kept their design simple with a total of 3 parts. They designed their lateral co
