2) In the figure below, covers of a bearing are tightened to the body with 2 fasteners. One of the bolts is shown in detail. Load $F_y$ is carried by 2 bolts equally. $F_x$ load acts to the system due to bearing load $F_y$ and its position is given in the figure. Dimension of bolts; M8x60 Pitch = 1,25mm, Pitch (effective) diameter of bolt $d_2 = 7,188$ mm Cross-section area of the bolt $A_c = 36,6$ mm$^2$ $l_1 = 12$ mm $l_2 = 38$mm Dimension of the sleeves; $D_o = 13$mm $D_1 = 9$mm $l_m = 25$mm Cross-sectional area of the bearing covers which are also included system deformation can be determined by using $A_p = \left[\frac{\pi}{4}(D_o + \frac{l_2}{10})^2 - D_1^2\right]$ relation. Also $l_p = 22$mm. Bolts, sleeves and covers are made of steel and their modulus of elasticity is $E_b = 2,1.10^5$ N/mm$^2$ a) Determine stiffness of the bolt, sleeve and cover which are tightened (effective length of the bolt is $l_1 + l_2$) b) Initially bolts are tightened to obtain a preload of $F_{pre} = 20$kN, in this situation calculate required tightening moment $M_t = ?$ Bolt head friction diameter is assumed to be $r_t = 0,7d$ and $\mu$ can be taken as 0,15 for all surfaces. c) Calculate the reduced load value ($F_2 = ?$) on the connected part and maximum load on the bolt, in case of an external force $F_x = 15$kN being applied to each bolt joint. d) The value of the $F_y$ force dynamically varies between 0 and a maximum value. Allowable dynamic stress of the bolt is $\sigma_{ads} = 50$ N/mm$^2$. What is the safety factor of the bolt in dynamic load range? Answer_2 a) $k_b = 1,94x10^5$N/mm , $k_s = 5,8x10^5$N/mm , $k_c = 1,12x10^6$N/mm b) $M_t = 33$ Nm c) $F_2 = 1720$N $F_{max} = 21720$N d) s = 2,14

Problem 9-14 Problems with IRR [LO5] Light Sweet Petroleum, Inc., is trying to evaluate a generation project with the following cash flows: Year Cash Flow 0 $-39,600,000 1 63,600,000 2 -12,600,000 a-1 What is the NPV for the project if the company requires a return of 12 percent? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) NPV a-2 Should the company accept this project? Yes No b. This project has two IRR's, namely percent and percent, in order from smallest to largest. (Note: If you can only compute one IRR value, you should input that amount into both answer boxes in order to obtain some credit.) (A negative answer should be included by a minus sign. Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

Which example BEST shows how "chunking" benefits memory performance? The names Terry, Bob, Bill, Jack, Fred, Sam, Anthony, Ed, Peter, and Michael are more likely to be remembered if they are alphabetized. A long list of words is better remembered if the words are organized categorically. The numbers 1, 4, 9, 2, 1, 7, 7, 6, 1, 9, 4, and 1 are more likely to be remembered if memorized as "1492," "1776," and "1941." A face is more likely to be later remembered if its individual features are studied carefully.
