and the temporal change of the temperature profiles is plotted the parameters used in the examples are listed in table 2 while not wishing to be tied to a particular theory it is believed that the differences between the temperature profiles of these two tmas are due to inhomogeneous distributions of heat along the contoured tma 34 in fig2 a and 2b the x axis and y axis represent the position and temperature along tmas 34 30 respectively in both cases the two ends of the beams are assumed to be attached to a heat sink maintained at room temperature starting from t 300 u00b0 k room temperature each temperature profile is offset by a 0 2 milli second time interval by qualitatively comparing examples a and b it is found that the contoured beam has a slightly larger thermal time constant which is expected because the heat generated at both ends of the contoured tma 34 would require some time to reach equilibrium state it is also found that the average temperature on the contoured beam rises faster than the straight beam which indicates that for identical input power the contoured tma has a higher forward stroke speed quantitative observation and calculations may be done based upon fig2 a and 2b by calculating.
