Dr. Yeomans said 90percentt of comets were classified into two categories: those like Halley's comet, which come from far outside the solar system and give off many carbon compounds, and those like Borrelly, which originate in a belt of comet material near Pluto's orbit and give off more water and ammonia than carbon.
In Van de Graaff generators, electric charge is transported to the high-voltage terminal on a rapidly moving belt of insulating material driven by a pulley mounted on the grounded end of the structure; a second pulley is enclosed within a large, spherical high-voltage terminal.
Another possible scenario associates the X-ray emission with a spherical explosion where parts of the ejecta are interacting with a dense belt of ambient material.
There are changing force conditions in the conveyor belt during transport of material using the pipe conveyors.
The reduced material loss in this situation is probably due to contaminants being effectively removed from the abrasive contact area owing to the belts of soft material and the grooves on the surface of the journal.
In 2003, imaging of the inner region of the Beta Pictoris system with the Keck II telescope revealed the presence of several features which are interpreted as being belts or rings of material.
Also, the free vibration analyses for various parameters of a belt driven system are made, including the tension of a belt, the length of a belt, the material properties of belts, the belt velocity and the pulley mass.
Scientists believe the bodies in the asteroid belt are the remnants of material that failed to form into a planet in the early years of the solar system, perhaps because of the gravitational influences of giant Jupiter.
They are back belts, the wide swaths of material that many people cinch around their waists when they lift heavy materials.
This paper presents a concise methodology to predict the flexural fatigue life of tooth V-belt through a combination of material property test and finite element analysis method.
