Question Q.3:A portal frame ABCD is fixed at A and D, and is loaded as shown in figure below. Treating joints B and C as rigid, calculate the moments at A, B, C and D. Draw the bending moment diagram and sketch the deflected shape of the frame. Take El=constant 25KN/m бm B 3m 3m

Consider the structure and applied actions shown in the adjoining figure. The frame is subjected to a uniformly distributed load on CD, a change in temperature in AB and support settlement at D. Use the dimensions and load values in the table below. Analyse the structure for all actions acting applied simultaneously and determine the reactions, member forces and displacement required in the table below.

Calculate the linear combination. 9(i + 2)) - 3(2j+ k) + 7(26 - 1) = (x, y, z) (Give your answers as a whole or exact number.) y =

The goal is to test whether the water 'diet' leads to a mean weight loss. (Hint: the differences have the mean of 7.25 and the standard deviation 10.500) A. Give a value for the test statistic, to 2 places past the decimal. B. How many degrees of freedom are there? C. Construct a 99% confidence interval for the mean weight loss. Give answer to TWO places past the decimal place. Lower Limit: Upper Limit: The water diet requires one to drink two cups of water every half hour from when one gets up until one goes to bed, but otherwise allows one to eat whatever one likes. Four adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are 1 2 3 4 175 122 237 159 Person Weight before diet Weight after six weeks Difference 164 126 217 157 11 -4 20 2

Critically evaluate the international marketing strategy of a company of your choice. It is expected that your company will be a major multi-national company operating in most of the major markets of the world. Thus you can choose companies from different industrial sectors, for example: Wal-Mart and Tesco in retailing This assignment entails the identification of the company’s mission statement and the role of internationalization in its business strategy. The main concepts of international marketing should be applied to your case company. Your report should include: The company’s motives for international growth The markets targeted The methods of market entry Unique strategies to adopt during the current VUCA (Volatile, Uncertain, Complex and Ambiguous) world The implementation of the marketing mix should be discussed and the success or otherwise of its international strategy should be evaluated.

The following equations were estimated using the data in BWGHT.RAW: log(dbwght) = 4:66 (:22) ?? :0044 (:0009) cigs + :0093 (:0059) log(faminc) + :016 (:006) parity + :027 (:010) male + :055 (:013) white n = 1; 388;R2 = :0472 and log(dbwght) = 4:65 (:38) ?? :0052 (:0010) cigs + :0110 (:0085) log(faminc) + :017 (:006) parity + :034 (:011) male + :045 (:015) white ?? :0030 (:0030) motheduc + :0032 (:0026) fatheduc n = 1; 191;R2 = :0493 The variables are dened as in Example 4.9, but we have added a dummy variable for whether the child is male and a dummy variable indicating whether the child is classied as white. (i) In the rst equation, interpret the coecient on the variable cigs. In particular, what is the e ect on birth weight from smoking 10 more cigarettes per day? (ii) How much more is a white child predicted to weigh than a nonwhite child, holding the other factors in the rst equation xed? Is the di erence statistically signicant? (iii) Comment on the estimated e ect and statistical signicance of motheduc. (iv) From the given information, why are you unable to compute the F statistic for joint signicance

Learning Goal: To become familiar with the force method of analysis for axially loaded composite members. As shown, a concrete column is reinforced with four steel bars. The column has length L = 9.000 m and a radius r = 400.0 mm. The steel bars each have a diameter of d = 30.00 mm, and the magnitude of the applied axial force is P = 1250 kN Assume the plate on top of the column allows for equal distribution of the applied force over the entire column and is infinitely rigid. The modulus of elasticity for 200.00 GPa concrete is Ec = 29.0 GPa and the modulus of elasticity for the steel is Es = Using the force method of analysis for axially loaded members, determine the axial force in the one of the steel bars, Ps Express your answer to four significant figures and include appropriate units.
