Gear Ratios When two spur gears (or any other type of gears)are in mesh, the number of teeth in one geardivided by the number of teeth in the other iscalled the gear ratio.Teeth #1 Ã· Teeth #2 = Gear Ratio 2. Gear Ratios and Structures Henri deVick A bout 1000 years ago, three inventions weremade in Europe.peed of Rotation, RPM The spinning or rotational speed of a gear ismeasured in Revolutions Per Minute (RPM).If a gear spins completely around exactly 16times in one minute, itâs going 16 RPM. If itspins exactly 1000.9 times itâs going 1000.9RPM.
In good weather conditions, a wolf can smell its prey from about 1.75 miles away. As the pack of wolves moves closer towards the prey, they will maneuver ahead of the prey for final confrontation. Just by its a sense of smell, a wolf can find and identify other pack members.
Powerful Sense of Smell. The strongest sense for a shark is their smell. It is a common myth though that sharks can smell blood miles away and then they will find the person or animal that it is coming from. While sharks can smell blood, it often indicates to them that there is wounded prey they can easily overpower. It may surprise you to learn that the nostrils on a shark arenât used for smelling. In fact, they arenât even attached to their mouths. It isnât an instinct of killing that the blood is going to create in them. In fact, if they arenât hungry then they wonât even bother to look for the source of the smell. Some of the species though can smell and indicate even a single drop of blood in the water. This is just an example of how powerful their sense of smell really is.
