In a smalldisc test, a small, discshaped portion of a component is loaded until failure. The article "Optimizing the Sensitivity of the SmallDisc Creep Test to Damage and Test Conditions" M Evans and DWang, J Straln AnalysS: 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 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.
