Required information A ductile hot-rolled steel bar has a minimum yield strength in tension and compression of $S_{yt} = 60$ kpsi and $S_{yc} = 75$ kpsi. Using the ductile Coulomb-Mohr theory, determine the factor of safety for the states of plane stress. $\sigma_x = 18$ kpsi, and $\tau_{xy} = -9$ kpsi (Round the final answer to three decimal places.) The factor of safety is 2.478.

A wheel of radius 23 cm rotates around its center with a constant angular velocity of 6 rad/s. Consider the linear acceleration a of the point P. Which has a greater magnitude, the horizontal (tangential) or vertical (radial) component of the acceleration? (Horizontal & vertical are with respect to the page.) q52.png Group of answer choices The vertical is greater because the horizontal acceleration is zero The vertical is greater but the horizontal acceleration is not zero The horizontal is greater because the vertical acceleration is zero The horizontal is greater but the vertical acceleration is not zero The horizontal and vertical components have the same magnitude

This assignment is based on the case study "Breaking Barriers: Micro-Mortgage Analytics" which can be purchased from Harvard Business Publishing. Please refer to the syllabus for the link to access this case study. Please answer the following questions as detailed as possible. If you want, you can use Excel to answer these questions. (1) Examine the decision tree in Exhibit 8 and come up with a strategy which Ajay and his team should adopt to identify creditworthy customers early in the assessment phase. (2) Using the classification table in Exhibit 10, answer the questions below: (a) Given 100 load applicants who have been approved a loan, how many of them would the model be able to correctly predict as sanctions? (b) Calculate the proportion of actual rejects which have been incorrectly classified as sanctions. (3) Apply the CHAID decision tree on the 100 data point provided in Exhibit 11 and construct the confusion matrix (assume the cut-off is 0.8). Is it similar to the one provided in Exhibit 10? What are your conclusions regarding the CHAID decision tree results? (4) Using Keerthana's model in Exhibit 12, access the statistical significance of a candidate's ability to repay the loan. Hint: Assume IAR to be a good proxy for a candidate's ability to repay the loan. (5) Siddharth had a look at the regression model built by Keerthana and believes that there could be a better model. Is Siddharth correct? Justify your answer. (6) Using Siddharth's model in Exhibit 12: (a) Compute the odds ratios relating the probability of a sanction associated with a 5\% increase in LTV after adjusting for the other factors. (b) Jamuna currently lives in a rented accommodation in the city of Rewari and she has applied to Shubham for a home load. What are her chances of getting a loan sanction had she not been living in a rented accommodation, keeping all other factors constant? (7) Use the data for two applicants in Exhibit 14 and derive the probability of sanction for each of them by applying Siddharth's model. (8) Exhibit 15 contains the confusion matrix for the training dataset at different cut off values. (a) Examine the table and suggest a suitable cut off point for Siddharth's model. (b) Using the optimal cut off point obtained from above, predict the decisions that Shubham would take with respect to applications in Q7. (9) Using Siddharth's model, calculate the profit/cost for correct and incorrect decisions during the application processing stage.

A conjunctive normal form (CNF) is a boolean expression which is a conjunction of disjunctions. For example, $\alpha = (a \lor b) \land (\bar{a} \lor b \lor c)$ is such a CNF where $\bar{a}$ denotes negation of the boolean variable a. A truth valuation $v$ that makes $v(\alpha)$ True is given by $v(a) = v(b) = v(c) = $True. It turns out, but we forego the proof, that every formula can be written in a conjunctive normal form with three literals (either variables or their negations) in each clause. We call such a formula a 3-CNF formula. (a) Give an explicit truth valuation (that is truth values for each of the variables below) for the following formula that make the formula evaluate to true: $\beta = (a \lor b \lor c) \land (a \lor b \lor \bar{c}) \land (\bar{a} \lor b \lor c) \land (\bar{a} \lor b \lor \bar{c}) \land (\bar{a} \lor \bar{b} \lor c) \land (a \lor \bar{b} \lor c) \land (a \lor \bar{b} \lor \bar{c})$

International Trade: End of Chapter Problems 2. For the following trade relationship, explain the likely source of the comparative advantage of each of the exporting countries. a. The United States exports software to Venezuela, and Venezuela exports oil to the United States. The United States has an endowment of oil, but software development depends on human capital, which the United States has in abundance relative to its oil reserves. Although Venezuela has an absolute advantage in oil production, the United States has a comparative advantage in both oil and software. The United States has a comparative, but not an absolute, advantage in oil production, and Venezuela has an absolute, but not a comparative, advantage in software production. The United States does not have domestic supplies of oil, and it is more efficient for Venezuela to use its resources to supply oil rather than software.
