✦ Synopsis

probability of wheel climb commencing is calculated using Nadal's formula as a basis. In particular, the functional form of Nadal's formula is maintained with normal probability density functions used to describe the two arguments in Nadal's formula, namely contact plane angle and coefficient of friction at the contact point. The theoretical value of the probability of wheel climb commencing for a given lateral/vertical

force ratio value at the wheel j7ange-railhead interface is then compared with experimental results for positive angles of attack. Theoretical results for negative angles of attack are generated for several cases.
