Steven M. Cron
Steven M. Cron is a retired Michelin product research engineer and co-inventor of the Tweel. Cron began his engineering education with a BS Mechanical Engineering degree from the University of Missouri-Columbia in 1984. In 1985, he completed an MS degree in aeronautical engineering from the U. S. Air Force Institute of Technology at Wright-Patterson Air Force Base. He then continued with the Air Force for 6 years as a project engineer working on ICBMs and as an instructor of Engineering Mechanics at the US Air Force Academy. He began his career at Michelin in 1991 as a research engineer. He had initial assignments in the area of tire vibrations, specifically damped modal analysis of pneumatic tires via the finite element method. He began work on airless tire technology as early as 1997, with work on the Tweel occurring over the period 2000-2009. Although other airless tire concepts have been studied or attempted in the past, none has achieved the commercial success of the T ...

The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's Planetary surface, surface, absorbing ultraviolet Solar irradiance, solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between Daytime, day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% Carbon dioxide in Earth's atmosphere, carbon dioxide, and small amounts of other gases. Air also contains a variable amount of Water vapor#Water vapor in Earth's atmosphere, water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Missouri Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tire Industry People
A tire (American English) or tyre (British English) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, that is designed to match the weight of the vehicle with the bearing strength of the surface that it rolls over by providing a bearing pressure that will not deform the surface excessively. The materials of modern pneumatic tires are synthetic rubber, natural rubber, fabric, and wire, along with carbon black and other chemical compounds. They consist of a tread and a body. The tread provides traction while the body provides containment for a quantity of compresse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymer Scientists And Engineers
A polymer (; Greek ''wikt:poly-, poly-'', "many" + ''wikt:-mer, -mer'', "part") is a Chemical substance, substance or material consisting of very large molecules called macromolecules, composed of many Repeat unit, repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form glass, amorphous and crystallization of polymers, semicrystalline structures rather ...

Tweel
The Tweel (a portmanteau of ''tire'' and ''wheel'') is an airless tire design developed by the France, French tire company Michelin. Its significant advantage over pneumatic tires is that the Tweel does not use a bladder full of compressed air, and therefore cannot burst, leak pressure, or become flat. Instead, the Tweel's hub is connected to the rim via flexible polyurethane spokes which fulfil the shock-absorbing role provided by the compressed air in a traditional tire. Design The Tweel consists of a band of conventional tire rubber with molded tread, a shear beam just below the tread that creates a compliant contact patch, a series of energy-absorbing polyurethane spokes, and an integral inner hub structure. Both the shear beam and the polyurethane spokes can be designed to provide a calibrated directional stiffness in order to control both how the Tweel handles and how it handles loads. The inner hub structure may be either rigid or compliant, depending on the application ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timothy B
''Timothy B'' is the second studio solo album by Timothy B. Schmit, the bass guitarist and co-lead vocalist for the Eagles. The album was released in 1987 on MCA in the United States and Europe, three years after Schmit's debut solo album, '' Playin' It Cool'' and seven years after the demise of the Eagles. The album peaked at #106 on the ''Billboard'' 200 chart, and the single, " Boys Night Out", hit #25 on the ''Billboard'' Hot 100 chart, Schmit's best selling single. The album was produced by Richard Rudolph, and it was co-produced by Bruce Gaitsch. Background When Schmit was asked about why there were less notable musicians compared to his last album, he said "I decided to stay out of the real glamour studios and to keep the clientele down too. I did it on purpose mainly for less distractions. I mean I really knew what I wanted to do on this album and I decided purposely not to use my famous and semi-famous friends just to have it be more of what I can do on my own. And that' ...
