The difference between the two wheels is that the lettering on the inside of the wheel is untouched on the Inertia Lite wheel but is removed on the Ultra Lite wheel. The Pinewood derby car problem is treated in two different ways below: 1) using the equations of motion and 2) using energy. The basic rule * Stream-line body shape for aerodynamics and speed. Taking very light cuts (no more than 0.0015" per cut), Imperfections increase friction. The outer hub face uses a 2 stage cut. of the tread. Precision metalworking lathe and cut slowly and smoothly down to the zero point you set. When the wheel moves towards the car body, the hub cap contacts with the axle cap before the wheel can touch the car body. The "after" wheels weigh in at just under Make a Three-Wheeler: Raise one wheel about 1/16 inch higher so it never actually touches the track. The hub bores on all pinewood derby wheels have a slight taper. All of the supplies from the "simple wheel preparation Set up the chiller to blast cold air on the tool/wheel Since we do not reduce the width of the wheel, there is no need to trim this area to make it appear to have the same gap. following section describes techniques which are guaranteed to As an Amazon Associate I earn off of qualified purchases -https://amzn.to/3zrc8ltAs an Amazon Associate I earn off of qualified purchases -https://amzn.to/3S012evAs an Amazon Associate I earn off of qualified purchases -https://amzn.to/3olXlT3As an Amazon Associate I earn off of qualified purchases -https://amzn.to/3zthUmKEnjoy the Benefits Of Being A Marriott Bonvoy Member, Click the linkbelow to sign up -https://www.referyourchasecard.com/252/RCUTQWE2WRBuying Crypto?
