The beam is supported by double-shear pins at A, B, and C. The radius of all the pins are r = 9 mm. Hint: 1. Remember that rod BC is a 2-force member F1 F2 F3 F4 C d1 d2 d2 d2 d1 θ1 B A Values for the figure are given in the following table. Note the figure may not be to scale. Variable Value F1 20 kN F2 34 kN F3 39 kN F4 33 kN d1 0.75 m d2 2 m θ1 22 degrees a. Determine the magnitude of the normal force in rod BC, NBC. b. Determine the magnitude of the reaction force in pin A, |A|. c. Determine the average shear stress in pin A, τA. d. Determine the average shear stress in pin B, τB. e. Determine the average shear stress in pin C, τC. Round your final answers to 3 significant digits/figures. NBC = kN |A| = kN τA = MPa τB = MPa τC = MPa

How the relationship between the asset returns and the market returns can be estimated? How do you measure systematic risk? How will you represent a total risk, systematic risk and non-systematic risk using a regression equation?

2. The data in the accompanying table represent the concentration of glucose in the blood serum of an adult patient. On four consecutive days, a blood sample was drawn from the patient and analyzed in triplicate. The variance for a given sample is an estimate of the measurement variance while the day-to-day variance reflects both the measurement variance and the sampling variance. (20 points) \begin{tabular}{cccc} Day & \multicolumn{4}{c}{ Glucose Concentration, \( \mathbf{m g} / \mathbf{1 0 0} \mathbf{~ m L} \)} \\ \hline 1 & 62 & 60 & 63 \\ 2 & 58 & 57 & 57 \\ 3 & 51 & 47 & 48 \\ 4 & 54 & 59 & 57 \\ \hline \end{tabular} a. Perform an analysis of variance and see whether the mean concentrations vary significantly from day to day.

A firm produces and sells two goods X and Y. Both goods sell for a price of $1 each. The production function for good X is $X = L_X^{1/2}$ The production function for good Y is $Y = L_Y K^{1/2}$ The firm divides its labour between the two products, $L = L_X + L_Y$, and gets its labour for free, but can only use 10 units of it or less $L \le 10 \implies L_X + L_Y \le 10$ The price of capital is $P_K = 2$ How much labour should the firm use to produce good X? $L_X = $ Number How much labour should the firm use to produce good Y? $L_Y = $ Number How much capital should the firm use? $K = $ Number How much of good X should the firm produce? $X = $ Number How much of good Y should the firm produce? $Y = $ Number How much profit does the firm make? $\pi = $ Number
