The numbers published in the tables were obtained from the 1998 CODATA least-squares adjustment of their values carried out in the Fundamental Constants Data Center at NIST in 1999. 5 and 6) assumed that tire deformation is a linear addition of equation 4 and equation 5, and proposed equation 6 to predict the total tire energy loss where A, B and C are empirically determined constants. |
