A sprag clutch is a one-way freewheel clutch. It resembles a roller bearing but, instead of cylindrical rollers, non-revolving asymmetric figure-eight shaped sprags, or other elements allowing single direction rotation, are used. When the unit rotates in one direction the rollers slip or free-wheel, but when a torque is applied in the opposite ...
A completely new design with a much larger cab, the Transtar cab would be shared with the all-new Paystar introduced in 1973. In 1985, the Transtar 4370 saw a major update and a renaming. Dropping the Transtar name, it became the International 9370, an introductory model of the International 9000 series. In 2000, the cab saw a major redesign ...
In mathematics, the special orthogonal group in three dimensions, otherwise known as the rotation group SO(3), is a naturally occurring example of a manifold.The various charts on SO(3) set up rival coordinate systems: in this case there cannot be said to be a preferred set of parameters describing a rotation.
Transtar, Inc. is a subsidiary of US Steel. It was organized in 1988 to own US Steel's railroad and other transportation subsidiaries. In the third quarter of 2021 it will be taken over by Fortress Transportation and Infrastructure Investors .
The Transtar name continued to be used on most of the 1957-58 3E series trucks, though a stripped-down Studebaker Scotsman model without the Transtar name was introduced in the 1958 model year. The 57-58 Transtars received an aggressive new fiberglass grille that attempted (largely successfully) to make Studebaker's outdated cab design look ...
Every non-trivial rotation is determined by its axis of rotation (a line through the origin) and its angle of rotation. Rotations are not commutative (for example, rotating R 90° in the x-y plane followed by S 90° in the y-z plane is not the same as S followed by R ), making the 3D rotation group a nonabelian group .
A range table was a list of angles of elevation a particular artillery gun barrel needed to be set to, to strike a target at a particular distance with a projectile of a particular weight using a propellant cartridge of a particular weight.
In mathematics, a rotation map is a function that represents an undirected edge-labeled graph, where each vertex enumerates its outgoing neighbors.Rotation maps were first introduced by Reingold, Vadhan and Wigderson (“Entropy waves, the zig-zag graph product, and new constant-degree expanders”, 2002) in order to conveniently define the zig-zag product and prove its properties.
