When People Turn Cranks That Cause Flags to Revolve Via

Question

When people turn cranks that cause flags to revolve via gears
A) The people can easily generate complex rotation ratios if the seen rotation ratios are complex
B) The people can easily generate simple rotation ratios if the seen rotation ratios are simple
C) The people can easily generate complex rotation ratios if the seen rotation ratios are simple
D) Both b and c

Accepted Answer

If the seen rotation ratios are simple, the people can easily match the rotation of the crank to the rotation of the flag by choosing a simple ratio. However, if the seen ratios are more complex, the people may need to experiment and find a combination of rotations that work, which could result in more complex ratios being used. So both B and C are correct.
