Item Subject: cc:Mail Text Dear Michael, please put me in your will for your AUDI. The game is braking and evasive action. Anyone with winter driving skills can GO fast. As the noted Stanley Michael Baker Hailwood was quoted " on an 'interesting' course, it's not the power it's the handling" After he smashed all comers at the Isle of Man after his return to MC racing. On ice the maneuvering boundary is the ice surface. On an ice surface, energy dissipation is as you might expect, by heat. If the specific heat necessary for a phase change to water is available a molecular layer of water is produced which acts as a lubricant between the rubber and the ice. The stiction graph takes an interesting downward excursion as this condition occurs. Stiction is if I recall a function of the friction coefficient and the downward or normal force. You and I can control only one variable, the heat dissipation. This is proportional to the braking energy required or mV**2 where m is the mass of the vehicle and V is the velocity of said mass. Studs work by allowing the crystalline destruction of the ice to take some but not ALL of the energy. When the system operates in the lubricated area the effectiveness of the brakes is dramatically reduced as the stiction turns to lubricated sliding.
