the in-plane micro-motions of the precision positioning stage are measured by using the proposed combined approach.The maximal bias of this new approach reaches 12.5 nm for motions near 2 000 nm.Experimental results show that the new combined method can measure the in-plane micro-motions with ...
Indeed, in this case, motion of the system about G reduces to a 3D-rotation, as further discussed in Chapter 2, subsection 2.2.2. 1.2.3.2 Plane rotation of a particle Polar coordinates (r,θ) are often used to describe motion taking place in a plane; see Figure 1.18. The following ...

We can generalize the above expression for any number of arbitrary mass points in the plane of the page that are rigidly connected and any number of applied force couples (torques), i.e., (1.3-3)(∑jrj2mj)ddtθ˙z(t)=∑jTθz j(t) The term in the parenthesis is referred to as ...

You can apply motion path animation effects to move slide objects in a sequence that tells an effective story. For example, the plane on the right (below) shows the starting point of the plane, and the dotted line between the two planes shows the path it will take when the animation p...

The equation of motion is obtained and solved for one degree of freedom φ. In9, the relative periodic solutions of a rigid body suspended on an elastic string in a vertical plane are considered. The equations of motion are obtained and solved in terms of the small parameter ε. ...
While seated in a moving infant chair, infants were habituated to a display consisting of three vertical rods aligned in the fronto-parallel plane. The outer rods were stationary and the middle rod moved contingently with the infant chair. After habituation, two stationary test displays were shown...
