Abstract | Imposing the constraint that a mechanical system having two completely symmetric 3-D rigid bodies have zero total angular momentum, the angular velocities of these bodies are negatives of one another, and the transfer of this sytem from one position to another is nonholonomic. While Chow's theorem establishes the fixed-endpoint controllability of the system, this result does not explicitly exhibit any motions between a given set of endpoints. In the present work it is shown how to explicitly construct simple motions of this system on (0, 1) with arbitrary endpoints in SO(3)/sup 2/. In particular, using normalized quaternions to describe rotations, the author constructs, in terms of elementary functions, a continuous motion with the given endpoints; it consists of at most three successive motions during each of which the bodies rotate on fixed axes. It is assumed that the rigid bodies have coincident mass centers, that each has a completely symmetric mass distribution about its mass center, and that the inertia tensor of each body is the identity matrix.< |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
