screw axis sentence in Hindi

Examples

1. The instantaneous screw axis, or'instantaneous helical axis'( IHA ), is the axis of the helicoidal field generated by the velocities of every point in a moving body.
2. The six parameters that define a screw displacement are the four independent components of the Pl�cker vector that defines the screw axis, together with the rotation angle about and linear slide along this line, and form a pair of vectors called a "'screw " '.
3. When a spatial displacement specializes to a planar displacement, the screw axis becomes the " displacement pole, " and the instantaneous screw axis becomes the " velocity pole, " or instantaneous center of rotation, also called an " instant center ."
4. When a spatial displacement specializes to a planar displacement, the screw axis becomes the " displacement pole, " and the instantaneous screw axis becomes the " velocity pole, " or instantaneous center of rotation, also called an " instant center ."
5. A non-discrete screw axis isometry group contains all combinations of a rotation about some axis and a proportional translation along the axis ( in rifling, the constant of proportionality is called the twist rate ); in general this is combined with " k "-fold rotational isometries about the same axis ( " k " e " 1 ); the set of images of a point under the isometries is a " k "-fold helix; in addition there may be a 2-fold rotation about a perpendicularly intersecting axis, and hence a " k "-fold helix of such axes.
