What is the spoke of a wheel reaches from the center of the wheel to its rim if the circumference of the rim wheel is 42 inches how long is each spoke?
The formula for the circumference of a circle = 2πr. Where r is the radius and thus the length of a spoke. When 42 = 2πr then r = 42 ÷ 2π = 6.6845 inches. The length of each spoke is 6.6845 inches (4dp).
If the spoke of a wheel reaches from the center to the wheel to its rim if the circumference of the rim of the wheel is forty two inches how long is each spoke?
If this is a real-life question it can't be answered, as real rims and hubs have all kinds of shapes to them that mess up the measurements. IRL a spoke wouldn't reach all the way to the center for instance, it'd be attached some way off, at the hub flange. You'd also need to know what lace pattern is being used, as that affects spoke length. But if this was a maths question that isn't required to make sense then spoke length would be (42/pi)/2.
Suppose a bike wheel has a radius of 27 inches if the bike is rolling at 10 miles per hour through what angle does spoke turn in 1 minute?
10*1760*36 = 633600 inches in 60 minutes 10560 inches in 1 minute Circumference of bike wheel = 2*pi*27 = 169.6460033 inches 10560/169.6460033 = 62.24726663 revolutions of bike wheel in 1 minute 62.24726663*360 degrees = 22409.01599 degrees in 1 minute Therefore the bike's wheel spoke has turned through an angle of 22409 degrees in I minute, correct to 5 significant figures.
Will 5 x 100 fits on 5 x 112 bolt pattern?
Unfortunately not - as the numbers suggest, the spacing is different.
What origin does the word radius come from?
Radius is from the Latin root word radius, spoke of a wheel, a staff, a beam of light.
