Bike geometry parameters: wheelbase, steering axis angle, fork offset, and trail. Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail.
Road racing bicycle forks have an offset of 40–55 mm. [2] For touring bicycles and other designs, the frame's head angle and wheel size must be taken into account when determining offset, and there is a narrow range of acceptable offsets to give good handling characteristics. The general rule is that a slacker head angle requires a fork with ...
Bike steering axis angle, fork offset, and trail. A factor that influences how easy or difficult a bike will be to ride is trail, the distance by which the front wheel ground contact point trails behind the steering axis ground contact point. The steering axis is the axis about which the entire steering mechanism (fork, handlebars, front wheel ...
The Earles fork is a variety of leading link fork where the pivot point is behind the front wheel, which is the basis of the Earles' patent. [3] Patented by Englishman Ernest Earles in 1953, the design is constructed of light tubing, with conventional 'shock absorbers' mounted near the front axle.
Also called resource cost advantage. The ability of a party (whether an individual, firm, or country) to produce a greater quantity of a good, product, or service than competitors using the same amount of resources. absorption The total demand for all final marketed goods and services by all economic agents resident in an economy, regardless of the origin of the goods and services themselves ...
This vehicle was unlike either the safety bicycles or the boneshaker bicycles of the era in that it had zero degrees of steering axis angle and no fork offset, and thus did not use the principles of bicycle and motorcycle dynamics developed nearly 70 years earlier. Instead, it relied on two outrigger wheels to remain upright while turning.
Offset (computer science), the distance to (displacement of) an element within a data object; Offset (gears), the perpendicular distance between the axes of hypoid or offset-facing gears; Offset (geometry), see parallel curve; Offset (geophysics), the distance between a source and receiver of seismic or other geophysical readings
The argument begins from the observation that in equilibrium, total income must equal total output. Assuming that income has a direct effect on saving, an increase in the autonomous component of saving, other things being equal, will move the equilibrium point, at which income equals output to a lower value, thereby inducing a decline in saving that may more than offset the original increase.
