T5 retrofit conversion can maintain existing lighting levels with the higher efficiency of the T5 lamp. However, with kits that operates the lamp on the existing magnetic ballast, the efficiency drops and the lamp life is considerably shortened, as T5 lamps aren't designed to be operated on mains frequency but only on high frequency.
Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center of mass (inertia axis) is out of alignment with the center of rotation (geometric axis). Unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of ...
A Mooney viscometer MV 2000 Mooney Viscometer. A Mooney viscometer or rotating disk viscometer is an instrument used for measuring the Mooney viscosity of rubbers. [1] Invented in the 1930s by Melvin Mooney, [2] it contains a rotating spindle and heated dies, the substance encloses and overflows the spindle and the mooney viscosity is calculated from the torque on the spindle.
Poloidal direction (red arrow) and toroidal direction (blue arrow) A torus of revolution in 3-space can be parametrized as: [2] (,) = (+ ) (,) = (+ ) (,) = using angular coordinates θ, φ ∈ [0, 2π), representing rotation around the tube and rotation around the torus's axis of revolution, respectively, where the major radius R is the distance from the center of the tube to ...

The Forthing T5 HEV or 5 HEV is a hybrid electric variant of the T5 Evo. The HEV powertrain is a CT-E engine derived from Citroen engine technologies and developed by Dongfeng Liuzhou Motor Co., Ltd. with an additional two-motor hybrid assembly, and a 2kwh battery pack. [8] The Forthing 5 HEV was displayed during IAA 2023.
The scale was written in the early 1970s, and does not take into account changes such as the growth in weight of vehicles or the great reduction in numbers and change of type of railway locomotives, [citation needed] and was written in an environment where tornadoes of F2 or stronger are extremely rare, so little or no first-hand investigation ...
