Increasing the rotational inertia of the front wheel by increasing the speed of the vehicle and the rotational speed of the wheel will tend to counter the wheel flop effect. A certain amount of wheel flop is generally considered to be desirable. Bicycle Quarterly magazine states, "A bike with too little wheel flop will be sluggish in its ...
For a sample motorcycle moving at 22 m/s (50 mph) that has a front wheel with a moment of inertia of 0.6 kg·m 2, turning the front wheel one degree in half a second generates a roll moment of 3.5 N·m. In comparison, the lateral force on the front tire as it tracks out from under the motorcycle reaches a maximum of 50 N.
Wheelbase (measured between rotational centers of wheels) Bike geometry parameters: The wheelbase of a bicycle. In both road and rail vehicles, the wheelbase is the horizontal distance between the centers of the front and rear wheels. For road vehicles with more than two axles (e.g. some trucks), the wheelbase is the distance between the ...
Speed wobble (also known as shimmy, tank-slapper, [1] or death wobble) is a rapid side-to-side shaking of a vehicle's wheel(s) that occurs at high speeds and can lead to loss of control. It presents as a quick (4–10 Hz) oscillation of primarily the steerable wheel(s), and is caused by a combination of factors, including initial disturbances ...
As the early motorcycle industry progressed, larger tyre sizes accompanied larger engine displacements, so that by 1909–1914, 2 + 1 ⁄ 4 in (57 mm) section, 26 in (660 mm) diameter tyres were used on 250 to 350 cc (15 to 21 cu in) motorcycles, and 2 + 3 ⁄ 8 to 2 + 1 ⁄ 2 in (60 to 64 mm) section tyres appeared on motorcycles with ...
Wire wheels: Wire wheels#On motorcycles says only main article: Motorcycle construction#Wheels, but that is not a main article, it is a subsection. Bicycle wheel is a better article, but none of these 3 actually explains how spokes support the wheel pre-stressed w/compression. Copyedit : Expand : AGV (helmet manufacturer) Alpinestars; Arai ...
A script that lets the sprite say Hello, World! then stops the script in Scratch 2.0. In Scratch 2.0, the stage area is on the left side, with the programming blocks palette in the middle, and the coding area on the right. Extensions are in the "More Blocks" section of the palette. [22] The web version of Scratch 2.0 introduced project autosaving.
The Steffey motorcycle in 1902, essentially a bicycle with a two-stroke engine attached, used wooden, rims with wire spokes. [1] This style of wheel evolved into a stouter motorcycle-specific wheel, still with spokes, up to the 1960s and beyond. [2]: 134 In April, 1922, Borrani started production of motorcycle wheels with an aluminium rim. [3]
