Based on the following specification (Figure: 12), state whether the measured component would be accepted or rejected. Please give the reasons for your decision.
An experiment to determine the effect of four different types of engine oil (A, B, C, and D) on the rolling friction coefficient of a car speed has been conducted. Three brands of car (Honda, Toyota, and Mazda) were chosen, and each engine oil was tested twice on each car, producing the following ANOVA output in Figure 2. i) How many treatments involved? Write down all the treatments.ii) Identify the number of replication for each treatment. iii) Based on the ANOVA table above, find the values of W, X, Y and Z. iv) Test the interaction effect on rolling friction coefficient of car speed between the four different types of engine oil and the three different brands of car. v) Do we need to test for marginal effect? Give a reason.

Experience in non-destructive testing of 7075-T651 aluminum (Sy = 72 ksi, KIC = 22 ksi in1/2) pressurized pipes dictates that the minimum detectable longitudinal crack length is 10 mm. Thus, a longitudinal crack of length 10 mm could escape detection and be present at any time. The pipes transmit a flow of natural gas and the presence of a crack would not alter the internal pressure. What maximum internal pressure would you recommend? Neglect the pipe curvaturewhen determining the stress intensity factor.
