polar moment of inertia
11First moment of area — The first moment of area, sometimes misnamed as the first moment of inertia, is based in the mathematical construct moments in metric spaces, stating that the moment of area equals the summation of area times distance to an axis [Σ( a x d )] . It …
12True polar wander — is a phenomenon in which a planet or moon changes its orientation so that different points become the North and South Poles. This can happen when the two larger moments of inertia are near equal.The Earth is not a true sphere, and therefore has… …
13Torsion (mechanics) — In solid mechanics, torsion is the twisting of an object due to an applied torque. In circular sections, the resultant shearing stress is perpendicular to the radius.For solid or hollow shafts of uniform circular cross section and constant wall… …

15Hollow 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… …
16Subaru Impreza WRX STI — Infobox Automobile name = Subaru Impreza WRX STI manufacturer = Subaru parent company = Fuji Heavy Industries production = 1992–present class = Sport compact World Rally Car layout = Front engine, symmetrical all wheel drive assembly = Ōta, Gunma …
17Torsion constant — The torsion constant is a geometrical property of a beam s cross section which determines the relationship between angle of twist and applied torque.For a beam of uniform cross section along its length: heta = frac{TL}{JG} heta is the angle of… …
18Mini-Z — with a Lamborghini body. Mini Z is a brand name for a popular line of 1:28 scale electric radio controlled cars manufactured by Kyosho Corporation, a Japanese manufacturer of various radio controlled devices. Kyosho makes a huge number of… …

20Neutral axis — Beam with neutral axis (x). The neutral axis is an axis in the cross section of a beam or shaft along which there are no longitudinal stresses or strains. If the section is symmetric, isotropic and is not curved before a bend occurs, then the… …
