I created this file to be an SVG alternative to Image:Bohratommodel.png and Image:Bohr model Balmer 32.png. I did not draw the orbitals to scale like the latter diagram because I could not readily find information about the orbitals' radii. For some reason, the "+" on the nucleus is rendering off-centered. The SVG doesn't look like that.
The binary cam is a design for the pulley system of a compound bow. Craig Yehle, director of research and development at Bowtech Archery, received a patent [1] for the design on December 11, 2007. Bowtech started equipping its bows with the new cam design in the 2005 model year. [2] [3]
Archer Erika Jones shooting a compound bow at the 2013 Archery World Cup. The bow has the axle attaching the limb to cam mounted at the edge of the cam as opposed to the center. In modern archery, a compound bow is a bow that uses a levering system, usually of cables and pulleys, to bend the limbs. [1]
The compound bow, not to be confused with a composite bow, is a modern bow that uses a levering system, usually of cables and pulleys, to bend the limbs. The limbs of a compound bow are much stiffer than those of a recurve bow or longbow. This limb stiffness makes the compound bow more energy-efficient than other bows, in conjunction with the ...
limb-driven rest (equipment) – A drop-away rest that is mechanically linked to one of a compound bow's limbs. Longbow - A type of bow that is usually used for long shots; loose (practice) – The act of shooting an arrow from a bow (a.k.a. release) laminated bow (equipment) – A bow with different materials laminated together to make a ...
In the 1960s, he sawed the ends off a conventional recurve bow and then added pulleys to each end. [1] Allen experimented with a number of designs to apply for a patent on June 23, 1966, [2] and U.S. patent 3,486,495 was granted to him in December 1969. With the help of bowmaker Tom Jennings, he became the first manufacturer of compound bows ...

The riser is the center where the archer holds the bow. The limbs attach to the riser. The limbs are the parts of a bow that bend when the string is drawn. The string attaches at each end of the limbs and gives propelling force to the arrow. An archer can update their takedown bow with new limbs to take advantage of advancements in materials or ...
