Boat and Lighthouse (Trig Problem)

thingiverse

This model was based off of a question from the August 2015 Common Core Geometry Regents. When I used this question to review with my class, many students had trouble understanding what the question was describing. This model allows me to 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 will tighten 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 provide 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 you tilt in just right.
