Review
Learning Intentions Sucess Criteria To explore the basic mechanical functions of links and guides Sucess Criteria I can describe a link based on the the 4 characteristics I can identify rotational and translational guides
Schedule Notes on guides and links Examples Mini Lab- Scissor Analysis Lab Exam Discussion
Basic Mechanical Function Links: Connect two or more parts of a technical object. Guide: Controls the motion of a piece of a technical object.
2 Types of Guides Translational guide: Controls the motion of a part of an object in a rectilinear motion (straight line). EXAMPLES TRAIN TRACKS DRAWER SLIDES
2 Types of Guides 2. Rotational Guide: Controls the motion of a part of an object in a circular direction. Ferris Wheel Door Hinge
Practice Decide whether the images on your paper represent rotational or translational guides.
Links can be described based on 4 characteristics.
DIRECT OR INDIRECT? INDIRECT (SCREWS) DIRECT!
Removable or Non-removable?
RIGID OR FLEXIBLE? FLEXIBLE RIGID
COMPLETE OR PARTIAL? PARTIAL COMPLETE
Let’s Practice
Lab Exam You will be asked to create a prototype that will complete a task You need to understand the following concepts Raw materials, materials equipment Guides and Links
IMPORTANT DATES You CAN NOT miss school on these dates unless you have a doctors note! Day #1) May 19th- Individual planning Day #2) May 25th- Group planning/construction Day #3) May 27th- Construction/trials Day #4) May 31st- Evaluation (prototype complete) THAT ONLY LEAVES ONE CLASS FOR EXAM REVIEW!
Partners You pick one person and then I will make a group of 3-4 Record your choice on your paper.
