Siege Engine

  1. 1. Siege Engine Design Challenge A Technology Education Activity by: Mr. Presti
  2. 2. Constraints <ul><li>Must be made from materials provided by the teacher. </li></ul><ul><li>May use additional materials from home. </li></ul><ul><li>Catapult must be able to through a projectile 15 feet. </li></ul><ul><li>Catapult must be adjustable and be able to hit the target accurately. </li></ul><ul><li>Catapult must be similar in design to catapults you have learned about. </li></ul><ul><li>Catapult must have wheels and employ the same principles used by the catapults you learned about. </li></ul>
  3. 3. Materials Provided <ul><li>Lumber 3/4x1/4x16 </li></ul><ul><li>Rubber Bands </li></ul><ul><li>Dowels </li></ul><ul><li>String </li></ul><ul><li>Wooden Wheels </li></ul>
  4. 4. Informed Design <ul><li>Clarify the Design Problem </li></ul><ul><li>Research and Investigate the Problem </li></ul><ul><li>Generate Alternative Designs </li></ul><ul><li>Choose and Justify the Optimal Design </li></ul><ul><li>Develop a Prototype </li></ul><ul><li>Test and Evaluate the Design Solution </li></ul><ul><li>Redesign the Solution With Modifications </li></ul><ul><li>Communicate Your Achievements </li></ul>
  5. 5. The Process of Design <ul><li>Technology addresses many types of problems and their solutions. Some problems require both science and technology to be resolved. </li></ul><ul><li>Design is a creative planning process that leads to useful products and systems. </li></ul><ul><li>Design steps can be performed in different sequences and repeated as needed. </li></ul><ul><li>Design involves making a product or system and documenting the solution. </li></ul>
  6. 6. Principles of Design <ul><li>Functionality is the capability of a product, system, or process to fulfill its intended purpose. </li></ul><ul><li>Quality is the degree of excellence with which a product is made. </li></ul><ul><li>Ergonomics is the science of adapting the work environment to people. It involves designing products so they can be used easily. </li></ul>
  7. 7. Principles of Design (continued) <ul><li>Safety is an important element of any design because a product system, or process must be designed so that it is safe for consumers to use. </li></ul><ul><li>Aesthetics is the study of the way something looks and how it affects people’s feelings about it. </li></ul><ul><li>Maintainability is important in design to allow for access to certain parts for tasks such as cleaning or repair. </li></ul>
  8. 8. Solving Real-World Problems <ul><li>Sometimes, there are trade-offs between social and personal desires. </li></ul><ul><li>Design solutions should benefit society but have minimal impact on the environment. </li></ul><ul><li>Values and beliefs shape people’s attitudes toward technology. </li></ul>
  9. 9. Solving Real World Problems <ul><li>Engineers and designers must keep in mind how their solutions will affect society and the environment. </li></ul>Reduce damage to crops by insects. Can harm wildlife and the environment. Insecticides Enables people to travel long distances in a short time Passengers have little chance of surviving a crash. Airplane BENEFIT RISK Trade -Off
