How far will a wheel of radius 5 cm travel in two revolutions?

In each revolution, the wheel would advance 2 x pi x radius. Multiply this by the number of revolutions.


How many turns must a wheel of a diameter of 0.5 make to travel 100m?

To calculate the number of wheel rotations needed to travel a certain distance, we must first find the circumference of the wheel using the formula C = πd, where d is the diameter of the wheel. Given that the diameter is 0.5 meters, the circumference is C = π(0.5) = 1.57 meters. To travel 100 meters, the wheel would need to make 100 / 1.57 = approximately 63.69 rotations. Therefore, the wheel would need to make approximately 64 rotations to travel 100 meters.


How many turns would the smallest bicycle with tire diameter 0.76 inches have to make to go the same distance?

First you have to know the distance you wish to travel. Then you simply calculate the circumfrance of the tire. (2pie*radius) which would give you around 4.77 inches. Divide the distance you want to go by 4.77 and you get the proper amount of turns.


What is the radius of a circle with a circumference of 8?

Well to find the radius of that, you would divide 8 by pi- so about 2.55. that would be the diameter so the radius would be about 1.27


The spoke of a wheel reaches from the center of the wheel to its rim if the circumference of the wheel is 42 inches how long does each spoke need to be?

We've already had this question. If this is about a real bike it can't be answered, as the spokes never go to the precise center of the wheel. If this is about maths, then basic geometry states that circumference = diameter times pi. A spoke would be the radius, which is half of the diameter. Pi is usually held at 3.14, but the numbers just keeps coming. Circumference / Pi = diameter Diameter / 2 = radius Now do the rest of the homework yourself.

How many turns must a bicycle wheel make of radius 0.5m make to travel a distance of 100m?

Well, darling, to calculate that, you need to figure out the circumference of the wheel using the formula 2πr. So, for a wheel with a radius of 0.5m, the circumference would be π meters. To travel 100m, the wheel would need to make 100/π turns, which is approximately 31.83 turns. So, grab your helmet and start pedaling like there's no tomorrow!

How far DOES a rider travel on one turn of each ferris wheel?

The distance a rider travels on one turn of a Ferris wheel can be calculated using the circumference formula, (C = 2\pi r), where (r) is the radius of the wheel. For example, if a Ferris wheel has a radius of 20 feet, the rider would travel approximately 125.66 feet in one complete turn. The actual distance may vary slightly based on the wheel's design and any additional movement.


How far a wheel with a radius of 9 cm travel in three revolutions?

To find the distance a wheel travels in three revolutions, first calculate the circumference of the wheel using the formula (C = 2\pi r). For a radius of 9 cm, the circumference is (C = 2\pi \times 9 \approx 56.55) cm. In three revolutions, the wheel would travel (3 \times 56.55 \approx 169.65) cm. Thus, the wheel travels approximately 169.65 cm in three revolutions.


If the diameter of a wheel is one yard then its radius is how many inches?

Well, isn't that just a happy little question! If the diameter of the wheel is one yard, which is 36 inches, then the radius would be half of that. So, the radius of the wheel would be 18 inches. Just remember, there are no mistakes, just happy little accidents!


What equation would you to calculate the ideal mechanical advantage of a wheel and axle if the input force is on the axle?

The formula to calculate the ideal mechanical advantage (IMA) of a wheel and axle when the input force is applied to the axle is: IMA = Radius of wheel (Rw) / Radius of axle (Ra) Where Rw is the radius of the wheel and Ra is the radius of the axle.

320 rpm.


What is the radius of a wheel with a diameter of 27.6cm?

Oh, dude, the radius of a wheel is just half of the diameter, so you take 27.6cm and divide by 2 to get 13.8cm. Like, that's the distance from the center to the outer edge. But hey, who's measuring anyway, right?


How does the wheel radius affect the effort needed to turn the wheel?

A larger wheel radius typically requires less effort to turn the wheel because the larger radius provides a mechanical advantage, allowing the force to be applied further from the center of the wheel. This results in a greater leverage effect, reducing the amount of force needed to turn the wheel. Conversely, a smaller wheel radius would require more effort to turn the wheel due to the decreased leverage effect.


Can 23 inch rims fit a 1997 Buick Riviera?

I believe you would have to cut inner wheel wells to accommodate the larger rims your turning radius would diminish I love the way you can maneuver u- turns with stock 16-inch wheels.


What equation would use to calculate the ideal mechanical advantage of a wheel and axel if the imput force is applied to the axel?

The equation for calculating the ideal mechanical advantage of a wheel and axle when the input force is applied to the axle is: Ideal Mechanical Advantage (IMA) = Radius of Wheel / Radius of Axle where the radius of the wheel and axle are the distances from the center of rotation to where the force is applied.
