L-W North bridge builders finish in top 20 at regional contest
Thursday, February 5, 2015

The four Lincoln-Way North student bridge builders finished in the top 20 at the Regional Bridge Building competition held recently at the Illinois Institute of Technology in Chicago.

Allison Gerk, Brandy Huppert, Mike Meade and Shelbee Earnest finished in 3rd, 4th, 11th and 18th place respectfully.

The Regional Bridge contest is broken into three regions: South Suburbs, North Suburbs, and the City of Chicago.

In the South Suburbs Region, Lincoln-Way District 210 schools had the top 11 positions, according to Mike Murphy, physics teacher and chair for the L-W North Bridge Building contest.

Allison Gerk took home a third place trophy. Her efficiency was 2128. Her bridge weighed 22.56 grams (about the mass of 4 nickels) and held 48kg (about 106 pounds). The winning bridge is determined by efficiency.
The equation for efficiency is the mass held divided by the mass of the bridge. Efficiency states that the bridge held 2128 times its own mass, noted Murphy.

Murphy continued, It is great to see the students work on projects outside of the classroom and relate them to topics learned in the classroom. It was obvious from their designs and results, that these students devoted a lot of hard work and time into this project.

The four North students had placed in the top four positions at their school Bridge Building contest held in December. Over 100 students competed in the North contest.
