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. Straln Analys/S,2007:389-413) presents the results of a factorial experiment to estimate the effects of the properties of the disc on the time to fallure (in ms ). The data in the following table are presented as a \(2^{5}\) 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.
Compute the estimates of the main effects and the interactions.(Round the final answer to three decimal place.)
