Students taking CAD 1 (Computer Aided Design) in the Engineering program at McKay competed in designing and constructing the most efficient bridge made of balsa wood. The students were given the criteria and rules in early April. Next, they completed their designs using AutoCAD software to produce scaled drawings of their bridges. They were then sent home with their drawings, glue and balsa wood and given roughly 2 months to construct the bridge. Testing the bridges was completed this week. Students weigh their bridges, take pictures, and test it by hanging a bucket from the bridge and pouring sand into the bucket until failure (total destruction) has occurred. Then they compute the efficiency. (The weight of the bridge vs the weight it held).
Mr. Wenger the instructor says, “It is always interesting to see what they come up with.” This was a record setting class. The 1st place winner Justin Walker designed and constructed a bridge that only weighed 17.4 Grams, which is the lowest of all time for a winner. Congratulations to all these students. Their future in Engineering looks very bright.
The results are as follows:
1st place – Justin Walker- weight applied 49.4 lbs. Efficiency – 1289 lbs.
2nd place – Edouard Boyzo -weight applied 58.4 Efficiency – 858 lbs.
3rd place – Dylon Stover – weight applied 31.4 Efficiency – 801lbs
