How do you interpolate between two curves to find the stress concentration factor of a hole or fillet
Homework Answers
One of best unbiased approach to interpolate between values of two curves is taking appropriate weighted average.
Suppose a parameter P is known to you whose curve is absent in chart given to you. Let 'P_lower' and 'P_upper' be the nearest values of parameter below and above whose curves are available.
Using above values obtain stress concentration factor 'S_lower' and 'S_upper'.
Now find 'f' (fraction) such that:
P = f * P_lower + (1 - f) * P_upper
Obtaining this 'f' calculate interpolated value as follows:
S_equivalent = f * S_lower + (1 - f) * S_upper
'S_equivalent' is required interpolated value.

Which best describes Lazarus and Folkman’s two-factor stress theory? A. Stress depends on your level of perceived control and your commitment to your goals. B. Change is the key factor in stress. C. You experience alarm, then resistance, then exhaustion. D. You first perceive the degree of threat and then your coping resources, and the discrepancy is your stress level.
