Moment of Inertia Wheel

thingiverse

Here is an apparatus to explore the interplay between rotational motion and the moment of inertia. To use it you insert steel dowel pins into the various radial locations. This allows you to vary the mass distribution while keeping the total mass of the wheel fixed. It can be used as a pulley and multiple can be used to perform and angular momentum race down a ramp. Print Settings Printer Brand: LulzBot Printer: TAZ 6 Supports: No Post-Printing Clear Dowel Pin Holes Used a cylindrical file to clean up the dowel pins, but not necessary. Install the bearings Press-fit the bearing into the central hub. Then install the 5/16" threaded rod and use nuts with washers to secure the wheel. Materials Needed Materials Needed --8 dowel pins --2 skateboard bearings --5/16" threaded rod for mounting to post clamps --string or fishing line
