This week marked an exciting phase of final assembly and competitive testing within the Engineering class as students wrapped up major build stages and prepared for next-level demonstrations.
In the post titled “Week of 10/27–10/30” Kim shared that most of the week was spent finishing the structural build of their project and applying the first round of surface finishing. After welding the frame, the student ground and sanded all visible seams, then applied a matte black powder-coat finish. To complete the aesthetic, mounting hardware was upgraded to stainless steel. The final step involved audio-visual integration: the student routed LED strip lighting into hidden channels and ran a power test to ensure even illumination across the frame. Read the full post →
Meanwhile, in the post “10/27–10/31 Trebuchet” Ben and another student documented the build and trial of a wooded trebuchet for class competition. Following the completed assembly, the team conducted several test launches, adjusting sling length and counter-weight mass in 100 g increments. They discovered one setup repeatedly resulted in torque-induced wobble at the pivot point, so they redesigned the base plate, increasing thickness from 12 mm to 20 mm and adding corner gussets for rigidity. With that modification, the trebuchet achieved consistent launches past the 30-meter mark and will be competing next week. Read the full post →
The Sophomores were working during the week on coding and circuitry with Mr. Christy.
