In a small-disc test, a small, disc-shaped portion of a component is loaded until failure. The article "Optimizing the Sensitivity of the Small-Disc Creep Test to Damage and Test Conditions" (M. Evans and D.Wang, J. Strain Analysis, 2007:389-413) presents the results of a factorial experiment to estimate the effects of the properties of the disc on the time to failure (in ms). The data in the following table are presented as a 25 design. The factors are A: hole diameter, B. disc diameter, Cdisc thickness, D. punch head radius, and E. friction coefficient. Two other factors discussed in the article are not considered here.

Question
Transcribed Image Text:In a small-disc test, a small, disc-shaped portion of a component is loaded until failure. The article "Optimizing the
Sensitivity of the Small-Disc Creep Test to Damage and Test Conditions" (M. Evans and D.Wang, J. Strain Analysis,
2007:389-413) presents the results of a factorial experiment to estimate the effects of the properties of the disc on the
time to failure (in ms). The data in the following table are presented as a 25 design. The factors are A hole diameter, B.
disc diameter, C disc thickness. D. punch head radius, and E. friction coefficient. Two other factors discussed in the article
are not considered here.

If you were to design a follow-up study, which factors would you focus on? Explain. (Check all that apply.)
Check All That Apply
The largest effects are the main effects of A and C
The largest effects are the main effects of Band E
The largest interaction is the interaction between A and C
The largest interaction is the interaction of Band E
The main effect of D is larger than the main effects of A and C
The main effect of D is larger than the main effects of Band E
