Consider a circular hole in a plate with stresses σx = 23 MPa and σy = 85 MPa applied to the plate edges. Determine the maximum tensile stress in the plate.

For the flat bar in Figure A of Table 14.3, let t = 4ρ and b = 36ρ. Using Neuber’s nomograph (Figure 14.10), determine the value of Scc for the case where the bar is subjected to axial tensile load.

Methadone and buprenorphine are considered treatments for opioid use disorders.

This question will analyze data from the American National Election Study which is a survey of thousands of ordinary Americans. The variables used here are: – clinton.thermometer is a respondent’s rating of their feelings toward Hillary Clinton. The scale goes from 0 (extremely negative) to 100 (extremely positive) – party.id is a respondent’s party identification that goes from 1 (strong Democrat) to 7 (strong Republican) Consider the R code and output below: a) How do these regression results predict that clinton.thermometer will change if party.id is increased by 1 unit? b)  Conduct a formal hypothesis test at the α = 0.05 significance level to assess whether people with higher (more Republican) values of party.id tend to have different feelings toward Clinton on average than those with lower (more Democratic) values of party.id. Be sure to formally specify your hypotheses, describe your conclusion and briefly explain what you learned from this test. c) Form a 95% confidence interval for the slope coefficient on party.id. (you can round all numbers used in the calculation to the nearest tenth if you want to keep it simple, e.g. 1.2845 would round to 1.3; you may also use 2 as the critical value instead of 1.96)

This question will analyze the same ANES data as in the previous question, but presents a different regression specification. For this question, you should just interpret the results of the regression below (ideology.reg), ignoring the regression model in the previous question (reg1). The variables used here are:- ideology is a 1-7 scale on which respondents rate their own ideology (1 is “very liberal” up to 7 which is “very conservative”)- educ_years is the number of years of education a respondent has completed- female is a dummy variable for being female that scores 1 for females and 0 for males Consider the R code and output below:   a) How do the regression results on the previous page predict that ideology will change if educ_years is increased by 1 unit for a man? b) How do the regression results on the previous page predict that ideology will change if educ_years is increased by 1 unit for a woman? (you can round your answer to the nearest hundredth if you want) c) Conduct a formal hypothesis test at the α = 0.05 significance level to assess whether the relationship between education and ideology is the same on average for men and women. Be sure to formally specify your hypotheses, describe your conclusion and briefly explain what youlearned from this test.  

According to Incentive Salience Theory, what happens to the relationship between “wanting” and “liking” during chronic substance use disorder?

If you answered “NO” to any part of the previous question, then you should exit from this exam right now. Proceeding with an invalid test area and camera view or insufficient materials will lead to your session being flagged and render your test unacceptable (an unacceptable test means a test score value of 0-zero) If you answered “YES”, then you should now: briefly show all your blank papers (front and back) to the side view camera. briefly show your calculator (face of the calculator clearly shown, NO GRAPHICS CALCULATOR Permitted). Make sure you have enough paper (15+- blank sheets of paper) and appropriate writing utensils. You will NOT be allowed to add more once the exam is underway. If your papers are not shown to the webcam at the beginning of the exam, the exam will be flagged. If you leave the testing seat your exam will be flagged. Any flagged exam may render your exam unacceptable. After you finish showing your blank papers, click on “PROCEED”, and then the “Next” button below to begin. By proceeding on with this test you are agreeing to abide by and honor the ODU Honor Pledge:    “We, the students of Old Dominion University, aspire to be honest and forthright in our academic endeavors.
