"' Screw theory "'is the algebra and calculus of pairs of vectors, such as forces and moments and angular and linear velocity, that arise in the kinematics and dynamics of rigid bodies.
42.
The gust angular velocity components ( " p g ", " q g ", " r g " ) are defined as the variations of the linear velocity components along the different vehicle axes,
43.
The drive will synchronize the rotation speed to the reference speed of the wobble signal, allowing it to maintain an accurate linear velocity ( the speed of the track as it passes the laser ).
44.
CAV drives give speeds up to 30?at the outer edge of the disc with the same rotational speed as a standard constant linear velocity ( CLV ) 12? or 32?with a slight increase.
45.
This meant that its recording and playback speed decreased toward the edge of the disc ( like the Compact Disc and other digital formats ), to keep a more constant linear velocity and to improve playing time.
46.
Similar arrangements using optical heterodyning are also used in laser Doppler sensors for measuring the linear velocity of solids and for measuring vibrations of surfaces; the latter sensor is usually called a laser Doppler vibrometer, also abbreviated LDV.
47.
Recordings made on a cylinder remain at a constant linear velocity for the entirety of the recording, while those made on a disc have a higher linear velocity at the outer portion of the groove compared to the inner portion.
48.
Recordings made on a cylinder remain at a constant linear velocity for the entirety of the recording, while those made on a disc have a higher linear velocity at the outer portion of the groove compared to the inner portion.
49.
In due course of motion the particle will reach the light cylinder surface ( a hypothetical area where the linear velocity of rotation exactly equals the speed of light ), leading to the increase of the poloidal component of velocity.
50.
Where \ upsilon is the linear velocity of a point in the rotating object ( in units of distance / time ) and C refers to the circumference of the circle that this measuring point performs around the axis of rotation.
