Thomas Jefferson at 71 years of age wrote to John Adams (age 78) on July 5, 1814: “But our machines have now been running seventy or eighty years, and we must expect that worn as they are, here a pivot, there a wheel, now a pinion, next a spring, will be giving way; and however we may tinker them up for a while, all will at length surcease motions.” Taking Jefferson’s words literally, what lifetime stage did he talk about?

Continuity theory suggests as people age, they continue to view the self in much the same way as they did when they were younger.

Theodore Roosevelt built his reputation as a military hero on his participation in

Which of the following test techniques would allow the reliability engineer to do quantitative analysis of materials? 


The popcorn experiment, as presented in the reading material, does NOT demonstrate which reliability concept?

Find the first four terms of the binomial series for the function f(x) =  1/3

(05.03 MC) Determine the empirical formula of a compound containing 47.37 grams of carbon, 10.59 grams of hydrogen, and 42.04 grams of oxygen.In an experiment, the molar mass of the compound was determined to be 228.276 g/mol. What is the molecular formula of the compound?For both questions, show your work or explain how you determined the formulas by giving specific values used in calculations.

The following Weibull plot came from a popcorn experiment, where the power of microwave is set at 120%. 1, Please explain x and y axes in terms of the scales they used, and show how to find the value of characteristic life of this Weibull distribution. (10 points) 2. Choose a physical model for this accelerated life test and write down its equation. (10 points) 3. Another popcorn experiment was conducted at the power level of 110%. The Weibull plot is shown below. Use the characteristic life values from both ALTs to estimate regression coefficients of the acceleration model. (10 points)   4. The use stress level is at 100% power. Predict the characteristic life at the use stress level. (10 points) 5. Given that the shape parameter of Weibull distribution is 2.8 and it is constant under different stress levels. Under the use stress level, predict the lifetime at which probability of failure is 0.1. (10 points)

Use a Taylor series to estimate the integral’s value to within an error of magnitude less than 0.001.

In a cross-functional team environment, such as the Ford reliability improvement program, the reliability function can influence product reliability primarily by
