If you have been an Indianapolis race driver, you would use “slick” racing tires with no tread. On dry surfaces you would possibly get as high as zero.9 as a coefficient of friction, but driving them on moist roads would be harmful since the moist highway coefficient might be as little as zero.1 .. The coefficient of friction does not rely upon the load of an object.
Questions will take a look at you on matters like normal force and the coefficient of kinetic friction. The variation of raise and drag coefficient with angle of attack is proven below for a NACA 0012 and NACA 6412 profile .
