Assume, X Company Limited (XCL) is one of the leading 4th generation Life InsuranceCompanies in Bangladesh. The Company is fully customer focused. This Life insurance company areexperimenting with analysis of consumer profiles (to determine whether a person eats healthy food,exercises, smokes or drinks too much, has high-risk hobbies, and so on) to estimate life expectancy.Companies might use the analysis to find populations to market policies to. From the perspective ofprivacy, what are some of the key ethical or social issues raised? Evaluate some of them.

Tungsten is being used at half its melting point (Tm3,400C) and astress level of 160 MPa. An engineer suggests increasing the grain size by afactor of 4 as an effective means of reducing the creep rate.(a)Do you agree with the engineer? Why? What if the stress level were equalto 1.6 MPa?(b)What is the predicted increase in length of the specimen after 10,000hours if the initial length is 10 cm?

Starting with the simplest approximation, cos x = 1, add terms one at a time to estimate cos(/3) (see Problem 2 in Lecture 5). (a) After each new term is added, compute the true and approximate percent relative errors. Use a calculator to determine the true value. Add terms until the absolute value of the approximate error estimate falls below an error criterion conforming to two significant figures. (b) Rename M-file function Maclaurin.m (available in Files/Lectures/05) to Maclaurin_cos.m, modify, and adapt it for evaluating the Maclaurin series expansion for cos x. Implement fprintf inside while loop to display for each iteration the following output: iteration number, approximate value of cos(/3), true percent relative error, approximate percent relative error. Report your M-file and output results for cos(/3).function [fxa,fxt,et,ea,iter] = Maclaurin(x,es,maxit)% Maclaurin series of exponential function% [fxa,fxt,et,ea,iter] = Maclaurin(x,es,maxit)% input:% x = value at which series evaluated% es = stopping criterion (default = 0.0001)% maxit = maximum iterations (default = 100)% output:% fxa = estimated value% fxt = true value% et = true relative error (%)% ea = approximate relative error (%)% iter = number of iterations% defaults:if nargin < 2||isempty(es),es = 0.0001;endif nargin < 3||isempty(maxit),maxit = 100;end% initializationiter = 1; sol = 1; ea = 100;fxt = exp(x);et = abs((fxt - sol)/fxt)*100;% iterative calculationwhile (1)solold = sol;sol = sol + x^iter/factorial(iter);iter = iter + 1;if sol~= 0ea = abs((sol - solold)/sol)*100;et = abs((fxt - sol)/fxt)*100;endif ea= maxit,break,endendfxa = sol;end

Consider operation of an ideal thrust chamber operating at 11 km altitude (pa = 22.7 kPa). It has the following characteristics: Stagnation pressure 1 MPa Stagnation temperature 3200 K Throat area 0.035 m2 Exit area 0.7 m2 Propellant gas has 3 = 1.25 and molar mass (M) 12 (a) Verify that the exit velocity of the flow is supersonic. (b) Calculate the exit conditions (Mach number, velocity, pressure) of the jet (c) Determine the mass flow rate and the thrust generated (d) Calculate the characteristic velocity and the thrust coefficient if the thrust chamber described above were operated at sea level (pa = 101 kPa), will the exit jet be supersonic? Explain. If it is not, where will the shock be located: at the exit plane? Inside the nozzle? Again, explain.
