R5 please answer all problems and also write out all steps and reasoning. The second image shows the correct answers.

MULTIPLE CHOICE -The answer is one of the options below please solve carefully and circle the correct option Please write clear .

In your biomechanical testing lab, you perform a series of compression tests to determine the relationship between apparent bone density (p, units of g/cm³) and ultimate stress (ơult, units of MPa). Using the set of experimental measurements below, write an m-file to fit a power relationship of the form O uli = Ap to the data. Use the log transform method to linearize the system and data, followed by linear regression. Plot the data points and the power relationship on a single plot. Be sure to label your axes and provide a legend. Provide a printout of your m-file and a printout of the command window showing your results. Write down the best fit equation and box it. 8.76 5.25 4.26 5.51 3.88 18.45 2.09 13.72 5.42 2.17 Oult (MPa) p (g/cm³) 0.598 | 0.459 0.319 | 0.235 0.141 0.754 0.177 0.553 0.394 0.246

HW Matlab 1) Create a variable ftemp to store a temperature in degrees Fahrenheit (F). Write m-file to convert this to degrees Celsius and store the result in a variable ctemp. The conversion factor is C = (F —32) * 5/9. 2) Write m-file to generate a matrix of random integers of size 100 by 100 their values between 15 to 80. 3) Free fall of objects is given by y =5mgt? where a is the acceleration, v is the velocity, y is the distance, m is the mass of the object, g is the gravitational acceleration. Plot the distance and velocity of the object for 15 seconds after its fall from rest (y = 0). Take m = 0.2 kg.

I need help with this question. :)

A certain system contains three branches in parallel. One branch contains units A and B in series. A second branch contains units C and D in series. The third branch contains unit E alone. These non-identical units have constant hazard rates in order of their unit number of 0.1/year, 0.15/year, 0.2/year, 0.15/year, and 0.25/year. a) Draw a block diagram and compute the reliability of the system from the reliabilities of the individual units. b) Draw a signal flow graph. c) Identify the cut sets and the minimal cut sets. d) Find reliability of the system. e) Find the mean time to failure

Could you please fix my code it’s supposed to look like the graph that’s on the picture. But the lines do not cross eachother at the beginning. Could you make the lines look like the lines on the graph? Use this code in MATLAB and fix it. % Sample data for Diesel and Petrol cars carPosition = linspace(1, 60, 50); % Assumed positions of cars % Define your seed here seed = 50; rand('seed',seed); % Set the seed for reproducibility % Assumed CO2 emissions for Diesel and Petrol CO2Diesel = 25 + 5*cos(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Diesel CO2Petrol = 20 + 5*sin(carPosition/60*2*pi) + randn(1, 50)*5; % Random data for Petrol % Fit polynomial curves with a reduced degree of 2 pDiesel = polyfit(carPosition, CO2Diesel, 2); pPetrol = polyfit(carPosition, CO2Petrol, 2); % Generate points for best fit lines fitDiesel = polyval(pDiesel, carPosition); fitPetrol = polyval(pPetrol, carPosition); % Plotting the data figure; hold on; % Plot Diesel best fit line…

For all the following problems, 5. a) b) You need to show at least 3 iterations calculated manually with all steps. You do not need to include the M.files for the bisection method (bisect.m) and for false position (falspos.m). You must, however, show the command lines for the given functions with their variables and other parameters. Fanning friction factor For fluid flow in pipes, friction is described by a dimensionless number, the Fanning friction factor f. The Fanning friction factor is dependent on a number of parameters related to the size of the pipe and the fluid, which can all be represented by another dimensionless quantity, the Reynolds number Re. A formula that predicts ƒ given Re is the von Karman equation: 4log₁0 (Re√) - 0.4 = Typical values for the Reynolds number for turbulent flow are 10,000 to 500,000 and for the Fanning friction factor are 0.001 to 0.01. (a) Develop a function that uses bisection to solve for fgiven a user-supplied value of Re between 500 and…

For all the following problems, a) b) 4. You need to show at least 3 iterations calculated manually with all steps. You do not need to include the M.files for the bisection method (bisect.m) and for false position (falspos.m). You must, however, show the command lines for the given functions with their variables and other parameters. Zero-pressure specific heat of dry air Mechanical engineers, as well as most other engineers, use thermodynamics extensively in their work. The following polynomial can be used to relate the zero-pressure specific heat of dry air cp kJ/(kg K) to temperature (K): 11 0.99403 +1.671×10-4T + 9.7215-10-8T²-9.5838×10- Cp = T3+1.9520×10-14T4 (a) Develop a plot of cp versus a range of T=0 to 1200 K. (b) Use bisection to determine the temperature T that corresponds to a specific heat of 1.1 kJ/(kg K). (c) What will be the value of T if you use false position method? (d) What is the percentage error between the results of (b) and (c)? For both methods use maximum…
