Indonesia merupakan pasar sepeda motor no. 3 didunia setelah China dan Amerika. Pertumbuhan kendaraan roda dua bermesin atau lebih dikenal dengan sepeda motor di Indonesia menunjukkan grafik menanjak setiap tahunnya. Tercatat kenaikan penjualan pertahunnya 1 juta unit sejak tahun 2000 sampai dengan 2005. Tingginya angka penjualan produk kendaraan bermotor juga berimbas pada tingginya angka kecelakaan. Tercatat kenaikan angka kecelakaan sebesar 1000 pertahunnya dan itu terjadi di Jakarta. Untuk meminimalisir angka kecelakaan yang ada penulis berkeinginan untuk mengadakan sebuah penelitian dengan menggunakan bantuan metoda Quality function Deployment atau QFD, Adapun cara yang dipakai untuk meminimalisir aspek kecelakaan adalah dengan menjabarkan stabilitas dinamik yang dimiliki sepeda motor tersebut dengan menggunakan rumus-rumus yang berkaitan dengan perhitungan stabilitas sebagai acuan untuk mendapatkan keinginan pelanggan. Hasil dari penjabaran rumus yang berkaitan dengan stabilitas dinamik tersebut nantinya di jadikan acuan dalam pengujian dengan menyertakan para responden dan dilakukan survey untuk mendapatkan hasil perhitungan. Hasil perhitungan dari seluruh survey yang diadakan tersebut nanti nya akan digunakan dalam pengisian House of Quality, sehingga hasil yang dicapai adalah perlu ditingkatkan kapasitas dari silinder motor tersebut, dan juga pengembangan Shocbreaker yang lebih baik sehingga dapat meminimalisir angka kecelakaan pada masa yang akan datang.

Indonesia's motorcycle market leading is no. 3 world ranking data after China and the United States. The growth of motorcycle sales in Indonesia are shows increase on graph each year. The increase of sales is 1 million units peryear since 2000 until 2005. The high number of motorcycle sales also effect on the high number of accidents. For in case, in Jakarta, there are more than 1.000 accidents occur each year. This paper describes the way that is used to minimize the accident trough defining the dynamic stability of the motorcycle using some equation which is related with the topic as a reference for the customer desires. Results From the explanation of dynamic calculations will create in the future as an anchor reference and it will tested with survey include the respondents to obtain the calculation results. The result of the calculation of the entire survey, which was held used to fill the House of Quality. The result from the whole suvey is to achived better condition that it will be used to fulfill the House Of Quality. Which mean position and shape of the saddle on the motorcycle must be enhanced and also the shocbeaker in order to reduce the accident that will be happen on next future.

This book treats dynamic stability of structures under nonconservative forces. It is not a mathematics-based, but rather a dynamics-phenomena-oriented monograph, written with a full experimental background. Starting with fundamentals on stability of columns under nonconservative forces, it then deals with the divergence of Eulers column under a dead (conservative) loading from a view point of dynamic stability. Three experiments with cantilevered columns under a rocket-based follower force are described to present the verifiability of nonconservative problems of structural stability. Dynamic stability of columns under pulsating forces is discussed through analog experiments, and by analytical and experimental procedures together with related theories. Throughout the volume the authors retain a good balance between theory and experiments on dynamic stability of columns under nonconservative loading, offering a new window to dynamic stability of structures, promoting student- and scientist-friendly experiments.

ABSTRAK
Penelitian ini membahas mengenai perhitungan karakteristik dinamik pesawat N-245 matra lateral direktional, yang masih dalam tahap perancangan, guna menentukan sikap pesawat udara dalam beberapa kondisi terbang. Perhitungan ini dilakukan dengan tujuan akhir untuk memperkirakan apakah pesawat stabil dalam berbagai kondisi terbang dan juga akan dibandingakan dengan data hasil uji terowongan angin yang akan dilakukan di kemudian hari. Nilai-nilai turunan kestabilan dinamik yang dicari pada penelitian ini antara lain adalah nilai Cyp, Clp, Cnp, Cyr, Clr, Cnr, CydA, CndA, CldA, Cydr, Cndr, Cldr. Nilai-nilai turunan kestabilan dinamik tersebut dicari menggunakan perangkat lunak software Vortex Lattice Aerodynamics VLAERO dan menggunakan data dari pesawat N-230 sebagai pesawat pembandingnya. Vv hasil rekomendasi berdasarkan perhitungan memiliki nilai 0.21 lebih besar dari pada Vv pesawat pembandingnya.

ABSTRACT
This research will discuss about dynamic stability derivative estimation of N 245 aircraft so that we can know how the aircraft behave in various possible flight conditions. The goal of this estimation is to define whether the aircraft is stable or not in various possible flight conditions, and the data will be compared with the data that the company get from testing N 245 in the wind tunnel in the future days. The variables of aircraft dynamic stability derivative calculated in this research are Cyp, Clp, Cnp, Cyr, Clr, Cnr, CydA, CndA, CldA, Cydr, Cndr, Cldr. The variables of aircraft dynamic stability derivative calculated with the help of software named Vortex Lattice Aerodynamics VLAERO , and using N 235 configuration as a comparable units. Recomended Vv that just been calculated on this paper have more 0.21 more value than the comparable Vv from N 235.

This book presents, in a uniform way, several problems in applied mechanics, which are analysed using the matrix theory and the properties of eigenvalues and eigenvectors. It reveals that various problems and studies in mechanical engineering produce certain patterns that can be treated in a similar way. Accordingly, the same mathematical apparatus allows us to study not only mathematical structures such as quadratic forms, but also mechanics problems such as multibody rigid mechanics, continuum mechanics, vibrations, elastic and dynamic stability, and dynamic systems. In addition, the book explores a wealth of engineering applications.
