Blackboard mechanics with magnetic components
Blackboard Mechanics™ system consists of over 25 large, colorful, and easy to see components, fabricated of heavy gauge aluminum and stored in a foam cushioned wooden storage case. Setting up a demonstration is quick and simple. Levers, inclined plane, pulleys, simple machines, roller, friction block, weights, springs and scales mount on the blackboard surface by means of high quality magnets. In minutes students or instructors can set up over 30 different experiments. The dramatic demonstrations promote a clear understanding of basic concepts of mechanics. Equilibrium, resolution, and composition of concurrent forces, levers, torque, inclined planes, mechanical advantage, pulleys, simple machines, model of a crane, physical pendulums, spring systems, center of mass and friction are a partial list of possible demonstrations. Hang the masses, attach the scales, and let your students see the results for themselves. All components of the kit mount magnetically or with suction directly to your classroom blackboard and are large enough to be seen clearly from the back of a classroom or lecture hall. Units of measure, vector diagrams and explanations can be written on the board right next to your demonstration set-up. Using this unique kit, it is almost as easy to setup your demonstrations as it is to simply write with chalk. Seeing the principles of mechanics operate while you explain them adds tremendous visual impact and makes lectures more memorable and understandable.
