Objectives: (1) To gain a working knowledge of a more specialized type of modern bridge designed by civil engineers; (2) to improve research skills, including discernment of appropriate professional and academic sources; and (3) to improve writing skills in order to clearly express ideas. Neatness counts.
Please read the entire assignment below, before beginning the assignment. Write your answers neatly and legibly.
- If you are currently in the 11th or 12th grade, your assignment is to research the TIED ARCH (BOWSTRING) BRIDGE.
- If you are currently in the 9th or 10th grade, your assignment is to research the DECK ARCH TRUSS BRIDGE.
