The linear drive comprises a housing, in which a first component (1) is displaceably mounted via a gear in rotation about an axis or the first component is flexibly rotated in the housing in rotation about a longitudinal axis. A second component (2) rotatably connected with the first ...
The standard way to compute a rotation about an arbitrary axis through the origin is to concatenate five rotation matrices. This note shows how vector algebra makes it easy to rotate about an arbitrary axis in a single step. Figure 1 shows a point P which we want to rotate an angle θ...
A rigid body has six degrees of freedom, three of translation and three of rotation. The most general motion of a rigid body can be separated into the translation of a body point and the rotation about an axis through this point (Chasles' theorem). In the general case the rotation axis ...

Device (10) for the angular displacement of a component (2) which is provided to be rotatable about a rotation axis (20), particularly an arm rest, particularly fixed to a seat (4) and especially to or in a vehicle, wherein the device (10) having a first locking toothing (131) and...
On the other hand, Chasles' theorem states the most general displacement of a rigid body is equivalent to a translation of a generic point in the body, plus a rotation about an axis through that point (see Ref. [5]). Since the rotation portion is independent of the point selection, the...
A rotation matrix is a matrix used to rotate an axis about a given point. The center of a Cartesian coordinate frame is typically used as that point of rotation. Rotation matrices are used for computations in aerospace, image processing, and other technical computing applications. ...
1. the act of rotating as if on an axis e.g. the rotation of the dancer kept time with the music Synonym: rotary motion 2. a planned recurrent sequence (of crops or personnel etc.) e.g. crop rotation makes a balanced demand on the fertility of the soil ...
about an axis making an angle α with the applied field, the angular factor may be expressed3as the sum of its mean value ½ (3 cos2α – 1) (3 cos2γ – 1), where γ is the angle between the internuclear vector and the axis of rotation, and two time-dependent terms, (3/2...
projection effects: (a) the sunspot is mapped onto the surface of a sphere the size of the Sun, (b) this is rotated about the north-south axis to transform the sunspot to the central meridian, (c) this is in turn rotated about an east-west axis to transform the sunspot to disc ...
