Calculate the change in stress between successive changes of tint, and hence the average value of As. Calculate the change in AR in relative retardation between successive changes of tint. Hence calculate the photo-elastic constant C, using equation AR = C ASt (Which is obtained by writing equation R = C S t) for a change of tint and for the next change, and subtracting the two equations. Remember that t = thickness Force Average Force (N) Change of Tint Zera 300 0.300/2 150 N First 55 160 55 160/2 -107.5 N Second 250 110 250-110/2 180 N Third 300 75 300.75 -107.5 N Table 1: Results of the current as the potential difference is increased through a linear resistor From each set of values recorded the average force for each specific tint was calculated.
