Consider the rudder assembly of a radio-controlled model airplane. For the 19° position shown in the figure, the net pressure acting on the left side of the rectangular rudder area is p = 4.2(10-5) N/mm². Determine the required force P in the control rod DE and the horizontal components of the reactions at hinges Ay and By which are parallel to the rudder surface. (The positive y direction extends horizontally from the hinge axis AB along the rudder surface toward the rear.) Assume the aerodynamic pressure to be uniform. 34 17 11 B 34 BA 13 C.

Suppose there are two different algorithms, ALG1 and ALG2, for solving the same problem. The running time of ALG1 is \Theta(n \log n) for any instance. The best-case running time of ALG2 is \Theta(n) and the worst-case running time of ALG2 is \Theta(n^2). Which of the following is true? The running time for ALG2 is \Omega(n \log n). ALG1 is more efficient than ALG2. The running time for ALG1 is O(n). ALG2 is more efficient than ALG1.

The pulse rates of 151 randomly selected adult males vary from a low of 45 bpm to a high of 121 bpm. Find the minimum sample size required to estimate the mean pulse rate of adult males. Assume that we want 95% confidence that the sample mean is within 4 bpm of the population mean. Complete parts (a) through (c) below. a. Find the sample size using the range rule of thumb to estimate $\sigma$. n = (Round up to the nearest whole number as needed.) b. Assume that $\sigma = 11.6$ bpm, based on the value $s = 11.6$ bpm from the sample of 151 male pulse rates. n = (Round up to the nearest whole number as needed.) c. Compare the results from parts (a) and (b). Which result is likely to be better? The result from part (a) is the result from part (b). The result from is likely to be better because

The following diagram shows the movement of households in a certain country among three income groups-affluent, middle class, and poor-over the 11-year period 1980-1991, where a = 27.5, b = 7.2, c = 30.5, and d = 8.6. $72,000 (in 1994 dollars) $24,000 AFFLUENT a% b% MIDDLE CLASS d% (in 1994 dollars) C% POOR (a) Use the transitions shown in the diagram to construct a transition matrix (assuming zero probabilities for the transitions between affluent and poor). (Let 1 = affluent, 2 = middle class, and 3 = poor.) (b) Assuming that the trend shown was to continue, what percent of households classified as affluent in 1980 were predicted to become poor in 2002?
