Stall Speeds and Center of Gravity (C.G.) Q: Some stall speeds are specified with the occupants in the full forward CG position. This does not seem like itâs a conservative specification, i.e., if the occupants move rearward, that would tilt the plane backward, causing an increase in angle of attack, causing a higher stall speed.
Yes whiskers are used to help balance as well as feelers to help them judge space and help in the dark. A cats tail also helps them balance, my cat had lost his tail do to an â¦ injury and now he uses his whiskers more to help balance.
In addition to having sensory properties, a cat's whiskers are also a good indicator of his mood. When a cat is angry or feels defensive, the whiskers will be pulled back. Otherwise, when the cat is happy, curious or content, the whiskers will be more relaxed and pushed forward. But the whisker's primary use is to help a cat judge whether or not he'll fit through an opening. A cat's whiskers are roughly as wide as his body -- sort of a natural ruler. The whisker tips are sensitive to pressure. You'll probably see a cat stick his head in and out of an opening before he puts his body in. He's judging the width of the opening, and is determining if he can fit into it.
