In one revolution a wheel moves forward a distance equal to its circumference. This is because the wheel Always in contact with the floor.
1)A trundle wheel clicks everytime. What is the radius of the wheel
I really don't get this question
Please Help me Thank you :)
Neither do I. There seems to be some information missing.
C = 2rπ
Therefore:
C/2π = r
To find the radius of the trundle wheel, we need to understand what a "click" represents in this context. In trundle wheels, a click typically occurs when a certain distance is covered by the wheel. Each click indicates that the wheel has made a full revolution.
To determine the radius, we can follow these steps:
1. Measure the distance covered by the trundle wheel with a tape measure or a known distance.
2. Count the number of clicks it takes for the wheel to cover that distance.
3. Divide the total distance by the number of clicks to determine the distance covered in each click.
4. Finally, divide the distance covered in each click by 2π as the circumference is equal to 2πr, where r represents the radius of the wheel.
Let's say the distance covered by the trundle wheel is 10 meters, and it takes 20 clicks.
Distance covered in each click = 10 meters / 20 clicks = 0.5 meters per click.
Next, divide the distance covered in each click by 2π:
Radius = 0.5 meters per click / (2 * 3.14) = 0.0796 meters (rounded to four decimal places).
Therefore, the radius of the trundle wheel is approximately 0.0796 meters.
