Table 1.

Tibial (A_t) and vertebral (A_v) growth plate area values in mm² for rats, rabbits and calves having body weight 125 g, 1250 g and 45 kg respectively. These values were used to convert ‘nominal’ to ‘actual’ stresses according to the ratio between the initial estimates available at the beginning of the experiment, and the final values obtained from experimental animals at the time of dissection. Since the actual areas were not known until the end of the experiments, the spring forces for each animal was set to an expected ‘nominal’ value. (See Equation 1).

	Initial Estimate		Final Value
	At	Av	At	Av
Rat	17.3	9.9	19.0	9.0
Rabbit	100.6	-	110	-
Calf	3670	118	2600	115
