Consider what you know about circles as you answer the questions below.
What do you know about the lengths of the spokes of a bicycle wheel? Draw a picture of a bicycle wheel with spokes and explain what you mean.
Examine the picture of the bicycle wheel below. If a circle is perfectly symmetrical and the spokes all pass through the center point, how must their lengths compare?
The spokes are all the same length.
As a bicycle travels on flat ground, how does the center of its wheels (the hub) move? Explain and draw a picture showing what you mean.
If a wheel is spinning, does the center ever shift in height? How about its horizontal position?
Draw a diagram and think about the wheel's movement to figure out the center's type of motion.
