Pulley With 608 bearings

pinshape

The model presented contains the fundamental components necessary to craft a basic double rope pulley system. This demonstration serves as an effective means of illustrating the influence of gravity along with friction on a stationary object. It also provides students with a comprehensive understanding of how this mechanism played a significant role in driving innovation within society. Enjoy! Print Settings Printer: DaVinci 1.0 AIO Rafts: Doesn't Matter Supports: Yes Resolution: Any resolution will produce acceptable results. Infill: 100% Notes: Be cautious of layer separation, as this can significantly weaken the printed parts. When using ABS, account for shrinkage and avoid warpage to ensure optimal performance. Post-Printing If printed in ABS, immersing the parts in an acetone vapor bath will enhance their structural integrity. While not essential, this additional step adds a valuable touch. However, it is crucial to perform this procedure in a well-ventilated area away from students. Design Process I employed Tinkered, Meshmixer, and 123D to create this design. Standards NGSS Overview and Background Introduction The primary objective of this hands-on activity is to enable students to grasp the concept of energy transference and the effects of friction on a stationary object. By participating in this experiment, students will gain a deeper understanding of scientific principles. Supplemental information regarding the pulley's operation and its consequences can be incorporated into the lesson plan. Lesson Plan and Activity Experiment Establish the pulley system and have each student pull the rope. Conduct this exercise once with bearings and once without to demonstrate the distinction between the two scenarios. Explain that the bearings reduce friction, thereby facilitating easier movement of the pulley. The level of detail provided should be tailored to the students' grade level. Materials Needed Materials To execute this project, you will require two 608 bearings, some rope, a counterweight for the rope, and, of course, a printer to create these parts.
