Abstract

The slope on which a wheeled tractor will overturn can be calculated from the conditions for static equilibrium but the value obtained does not take into account the effects of rolling and pitching motions due to ground roughness and must be diminished to allow for these when estimating the maximum slope on which travel is safe. The interpretation of statistical measures of these motions is discussed and a procedure for taking them into account is suggested. This involves consideration of the period within which the first occasion of overturning is likely to occur and stipulation of the "first passage time".
