Making this substitution in the expression for Pi gives

sin 2 0

cos d Vf dVi

The factor, 1/ {4 sin2 0) is the initial mass multiplying effect of the linkage and, for the instant the bolt motion starts, expresses the ratio by which the retardation offered by the linkage mass exceeds that of an equal mass loeated at point A. For example:
