This is intended to be a slowly developing easy to follow discussion of the basic math, trig, and engineering/physics relating to motorcyle performance issues. Stay tuned... |

Probably a good general starting point is Sportbike Performance Handbook, followed up with a quick lap through Denish's and Buzzelli's books. This is the point where I just step back and listen and learn. |

Blake. Are we going to need to buy textbooks for this class? Can I use my GI bill? |

A start on understanding basic trig and vectors... The trig operators of Sine, Cosine, and Tangent are simply expressions relating the ratios of various sides of a right triangle (triangle with one 90 deg angle). A right triangle is composed of three angles (one of 90 degrees, and two of acute angles whose sume always equals 90 degrees) and three sides, the longest of which is opposite the 90 degree angle and is called the "hypotenuse". Two two acute (less than 90 degrees) angles are always adjacent to the hypotenuse and one of the sides and opposite of the other side. With respect to either of the triangle's acute angles, each of the two (non-hypotenuse) legs of the triangle can be referred to as "opposite" or "adjacent". The trigonemetric operators of Sine, Cosine, and Tangent are simply the ratios of the various lengths of the legs of a right triangle wrt a set acute angle. Sine (aka "SIN") = Opposite/Hypotenuse Cosine (aka "COS" = Adjacent/Hypotenuse Tangent (aka "TAN") = Opposite/Adjacent Why do we care about right triangles and the relationships between their angles and the ratios of the lengths of their sides? Vectors, the constant friend of all freshman engineers and physicists. Anything that can be defined by the two parameters of magnitude and direction can be represented by a vector. Like a force, velocity, torque, acceleration, and displacement; all have only magnitude and direction. The arrows on the free body diagrams yo usee me post every now and then are vector representations of forces. The length of an arrow represents the relative magnitude of the force and of course the arrow's direction represents the line of action of the force. |

Mike, this should be much more basic and scientifically technical than the references you mention. I think the above will give you a flavor for the direction I'm heading. Yeah, I know, I need some pictures. Dan: Heheh, only if you want pop quizes. If Anyone knows of of some good web pages already treating this in easy understandable fashion, I'm certainly not adverse to posting the links here. |

Sorry, I sent it via e-mail on another account to your badweb. It's about 146K. Posted to my website. This is the URL. http://www.gwsquared.com/MC_Physics.pdf Arvel Scheesh, I am so tired of computers right now. DONT USE XP PRO IF YOU HAVE ANY LEGACY SOFTWARE. |

Looks like hte first of the above links is broken. Too bad it was an interesting site about the physics of car racing Dave |

Hey Blake, Can you calculate the tangent on this one. Credit going to Tripper for his earlier post.
