(Carl) We have our bolt and thread here to balance and we can run the nut in and out to get the perfect balance. (Destin) That's pretty smart. I bet a smart guy came up with that. (Carl) oh.. a.. brilliant person. [laugh] Oh hey. Yeah. You see that? You see how awesome this is? Hey it's me Destin. Welcome to Smarter Every Day. We're continuing our ... Read More
Questions & Answers
Q: How does the laser replace helicopter blades in the experiment?
The laser is positioned in place of the blades, and a high-tech gadget is used to balance it. The laser represents the pitch changes of the rotor grip as it spins.
Q: What does the laser's orientation represent?
The laser's orientation represents the cyclic input of the helicopter. It tilts in different directions (right, left, forward, back) based on the input.
Q: What is gyroscopic precession?
Gyroscopic precession is a phenomenon where a force applied to a rotating object is felt 90 degrees later in the direction of rotation. In this case, it affects the laser's orientation and represents the helicopter's operational phase.
Q: What is the significance of visualizing pitch and gyroscopic precession?
This visualization helps understand how pitch changes during a revolution, and how gyroscopic precession affects the orientation of the helicopter. It provides valuable insights into the mechanics of helicopter flight.
