Summer Career Connections at SAVY 2018: Session 6, Day 1 – Kinematics for Mechanical Design (Rising 7th)
The first day of Kinematics for Mechanical Design is finished! We had a fabulous time getting to know one another, drawing, and learning about the kinematics (motion analysis) of pulley systems. Students have been given a three ring binder and drawing tools to sketch as well as formally draft their ideas. Each notebook has a pad of engineering paper, a pencil pouch, two drawing triangles that contain a protractor and a french curve, an architect’s scale, and the all-important Mars brand plastic eraser. We drew our names as a warm up and to personalize and decorate the front of our notebooks. Then we moved on to pulley systems with multiple objects and multiple pulleys.
We used math to analyze some example systems, and then we moved to some open space in the classroom to verify our analysis experimentally with string, binder rings, and two long tape measures. Some students acted as fixed pulleys and movable objects while others measured their positions and took down data. We plotted the results of our experiment and found they matched more or less with the theory! In the afternoon, we switched from analysis to design and figured out how to come up with a pulley system that moves the objects with a given speed ratio. Stay tuned for more to come!
