Chainring: (one of the) front gear(s), attached to a crank; Chainset: see Crankset; Chainstay: a pair of tubes on a bicycle frame that runs from the bottom bracket to the rear fork ends; Chain tensioner: a device to maintain proper chain tension; Chaintug: a device to aid in setting the proper chain tension
For rod length 6" and crank radius 2" (as shown in the example graph below), numerically solving the acceleration zero-crossings finds the velocity maxima/minima to be at crank angles of ±73.17530°. Then, using the triangle law of sines, it is found that the rod-vertical angle is 18.60639° and the crank-rod angle is 88.21832°. Clearly, in ...
Cranks can be shortened for medical reasons using shorteners such as Ortho Pedal. Unicycle cranks vary in length to accommodate different unicycle wheel sizes, and different unicycling disciplines. As almost all unicycles are ungeared, crank length is a major factor in determining how much force is transmitted to the wheel.

For example, for rod length 6" and crank radius 2", numerically solving the above equation finds the velocity minima (maximum downward speed) to be at crank angle of 73.17530° after TDC. Then, using the triangle sine law , it is found that the crank to connecting rod angle is 88.21832° and the connecting rod angle is 18.60639° from vertical ...
In the mathematical discipline of graph theory, a graph labeling is the assignment of labels, traditionally represented by integers, to edges and/or vertices of a graph. [1] Formally, given a graph G = (V, E), a vertex labeling is a function of V to a set of labels; a graph with such a function defined is called a vertex-labeled graph.
Many applications do not change the direction of motion but instead amplify a force "in line", which a bellcrank can do in a limited space. There is a tradeoff between range of motion, linearity of motion, and size. The greater the angle traversed by the crank, the more the motion ratio changes, and the more non-linear the motion becomes.
Dimensioned drawing of a slider-crank (left) and its kinematic diagram (right). In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as ...
