mass moment of inertia
61Gyro monorail — The gyro monorail, gyroscopic monorail, gyro stabilized monorail, or gyrocar all denote a single rail land vehicle, road or rail, which uses the gyroscopic action of a spinning wheel, which is forced to precess, to overcome the inherent inverted… …
62Bicycle wheel — For the Marcel Duchamp installation, see Bicycle Wheel. The front wheel from a racing bicycle made using a Mavic rim …
63Countersteering — For the similar technique used in automobiles, see Opposite lock. Graphs showing the lean and steer angle response of an otherwise uncontrolled typical bike, traveling at a forward speed in its stable range (in this case 6 m/s), to a steer torque …

65Bending — For other uses, see Bending (disambiguation). Flexure redirects here. For joints that bend, see living hinge. For bearings that operate by bending, see flexure bearing. Continuum mechanics …
66Hollow moon — The hollow moon theory is a pseudoscientific theory that suggests that Earth s moon is a large hollow sphere. Little published evidence exists to support the idea.Seismometer recordings from November 1969 are often cited as evidence against this… …
67Callisto (moon) — Callisto View of the heavily cratered terrain of Callisto s anti Jovian hemisphere obtained in 2001 by NASA s Galileo spacecraft. The large impact structure Asgard is on the limb at upper right. The prominent rayed crater below and just right of… …
68Post-glacial rebound — A model of present day mass change due to post glacial rebound and the reloading of the ocean basins with seawater. Blue and purple areas indicate rising due to the removal of the ice sheets. Yellow and red areas indicate falling as mantle… …
69Variance — In probability theory and statistics, the variance of a random variable, probability distribution, or sample is one measure of statistical dispersion, averaging the squared distance of its possible values from the expected value (mean). Whereas… …
70Beam (structure) — A statically determinate beam, bending (sagging) under an evenly distributed load. A beam is a horizontal structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the… …
