Boat and Lighthouse (Trig Problem)

thingiverse

This model was inspired by a question on the August 2015 Common Core Geometry Regents exam. When using this question to review with my class, many students struggled to grasp what the question was asking about. This model lets me show the student and let them experiment with the angle relationship in a very hands-on way: by attaching a rubber band between the hook on the ship and the hook on the lighthouse, the elastic rubber band tightens as the ship moves, forming the angle of elevation. Print Settings Printer Brand: FlashForge Printer: Creator Pro Rafts: No Supports: No Resolution: 0.20 mm Infill: 10% Notes: I used 3 shells to add extra strength in the hooks for holding the rubber band. When I printed the entire model, the boat came loose from the build plate. I reprinted just the boat and included that file. The boat slides in the channel and will slide out if tilted correctly.
