Concept explainers
One very old method of sending secret messages is to hide the message inside another (usually longer) message. A few possible cases are illustrated by the following questions.
a. Assume Loud=' THUNDERSTORM' ,
What is placed in Fate by the command Fate= Loud ( [5, 10, 1 0 , 121);
b. What is in Hidden after the following two MATLAB commands are executed?
C. Assume composer= 'Beethoven' ;
Replace a single letter in composer with a blank and place the result in the variable Root _crop_cooker . The contents of this new variable should be appropriate for the variable name.
d. Assume the following are defined:
What is placed in Msg by the following command?
e. You wish to send the secret message “April first” to a colleague. Conceal this message inside another text string stored in Hide. The string in Hide should be a complete sentence or phrase, not merely gibberish
For your answer, show both the MATLAB statement that creates Hide and the MATLAB command that would be used to extract the message hidden within and place it in Message.

- please write a matlab codearrow_forwardmatlab pleasearrow_forwardI wanted to create two spheres that overlap each other in MATLAB. The image has my code and results. I only see one sphere in the results. Why is that? Can you give me the code that will create two overlaying spheres in one plot?arrow_forward
- I was going over the equations for the notes in class and I had a thought. Based on the equations in the image, you could get negative propellant mass. So, I coded it in matlab and I got negative mass. How is that possible? I think I used practical values for the velocity and mass ratio and so on. Did I do something wrong?arrow_forwardMy professor said that I need to use the numbers as shown on the picture and make the exact graph that is also shown on the picture. But I don’t know how to put this in to MATLAB. Please send the code that makes the graph that is shown in the picture. Make it 100% exactly the same.arrow_forwardThe title of our study is "Design and Fabrication of an Agricultural Spraying Attachment for an Autonomous Rover" we need help in the machine design part of our study, specifically Pump selection, battery selection, and center of gravity computation I already sent you the image of the rover Rover weight capacity 35 kilo grams (payload) Rover measurements: Wheel distance - 14.5 inches and 8.5 inches Rover platform size (width & length) 14.4 inches x 10.4 inches Height- 15.8 inches. Water tank selection More or less 25 liters *For tank selection we need to justify the size with the center of gravity, proving that is the maximum dimension or liters of the tank because the center of gravity will be higher making the rover prone to toppling Pump selection *Our sprayer design has two nozzles which splits using a tee splitter, we need to find the size of the pump to obtain the same discharge rate of a normal sprayer. A normal sprayer has a 12V pump and a pressure from 0.2 to 0.45 mpa…arrow_forward
- Learning Goal: To use equilibrium to calculate the plane state of stress in a rotated coordinate system. In general, the three-dimensional state of stress at a point requires six stress components to be fully described: three normal stresses and three shear stresses (Figure 1). When the external loadings are coplanar, however, the resulting internal stresses can be treated as plane stress and described using a simpler, two-dimensional analysis with just two normal stresses and one shear stress (Figure 2). The third normal stress and two other shear stresses are assumed to be zero. The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are given in one coordinate system (Figure 3), the equivalent stresses in a rotated coordinate system (Figure 4) can be calculated using the equations of static equilibrium. Both sets of stresses describe the same state of stress. The stresses σx′and τx′y′ can be found by considering the free-body…arrow_forwardMake a matlab codearrow_forwardUse MATLAB please send code for this.arrow_forward

Please explain how to simplify. Thanks!arrow_forwardSuppose your CFD code can handle nonelementary blocks. Combine as many blocks of Fig. as you can. The only restriction is that in any one block, the number of i-intervals and the number of j-intervals must be constants. Show that you can create a structured grid with only three nonelementary blocks. Renumber all the blocks and indicate how many i- and j-intervals are contained in each block. Add up all the cells and verify that the total number of cells does not change.arrow_forward
