We called Hoosier to ask them about coefficient of friction data, and they said they didn't have the facilities to provide us with a approximation of the coefficient of friction for their R25A compound... As engineers do, we got a little crazy. Where g is the gravitational acceleration, v is the initial velocity when the brakes are applied and f r is the rolling resistance coefficient and was assume to be equal to 0.013. Unmatched corrosion, chemical and durability performance; Unique ceramic-polymer technology that imparts both flexibility and excellent physical performance; Find out … (Technical report) by "SAE International Journal of Engines"; Transportation industry Automobile engineering research Automotive engineering research Control systems Research Differential gears Design and construction Equipment and supplies Mechanical wear Wear (Materials … Friction is considered in two ways - longitudinal friction along the line of the road (or tangential to the curve of the road); and lateral… Coefficient Of Friction. We strive to always meet or exceed the needs of our customers in all aspects of our products and services, and maintain zero defects and 100% on-time delivery for all operations. :P Got some numbers though. hey is there anybody using hoosier tires of 20*6-13 R25A specification.....what's the coefficient of friction u r taking in calculating breaking force or any idea what will be the breaking force on front tires require if the front tire load is 215kg H Series (oven cure) 100+ Colors. The giant US Hoosier Racing Tire manufacturing plant is located in Plymouth, Indiana just south of the Corporate Headquarters in Lakeville and produces race tires 24 hours a day. • This distinctive multi-functional lubricating grease has very good mechanical stability (won’t thin out under normal usage), has excellent resistance to water wash out, clings to metal surfaces under severe conditions as it effectively reduces the coefficient of friction. It was during these early days that Bob had a vision to produce his own tires specifically designed for racing. There are two types of friction static friction (when the object is not moving) and kinetic friction (when the obje ct is moving). • Hoosier 18.0 x 7.5 10 R25B (Item 43105) Additionally, two constructions from Round 5 were partially re-tested, each on two different rim widths. Hoosier Gasket Corporation provides customers with 100% conformance to all specifications and requirements. We called Hoosier to ask them about coefficient of friction data, and they said they didn't have the facilities to provide us with a approximation of the coefficient of friction for their R25A compound... As engineers do, we got a little crazy. So the nature of that friction could actually be a matter of life and death. Find out more. Uses: Firearms, knives, eye wear, consumer electronics, salt water applications and more. this results in load, inclination angle, and inflation pressure sensitivity to coefficient of friction. In road tires, most of the friction generated is due to adhesion. Figure 2: Mechanisms of tire-road friction (Gillespie, 1992, p. 341) Adhesion is the result of intermolecular bonds between the rubber and the surface of the road and hysteresis represents energy loss in the rubber as it deforms when sliding over the bumps in the road surface. So in 1957 Bob and Joyce began their own business in an old abandoned horse barn in South Bend, Indiana selling tires to local racers... and Hoosier Racing Tire was born. Hoosier has established itself as a world leader in the manufacture of racing tires, materials and specialty compounds. But I guess we have more resources than Hoosier for tire testing. Based on the manufacturer's specification in conjunction with measurements from an actual tire.
