Chapter 18, Problem 22RQ
Write a MATLAB program that will allow the student to select the grade earned in a course from a menu (with the options of earning an A, B, C, D, or F) that will display the numerical range for the selected grade. The output of the program displayed on the screen should be formatted as shown in the sample output. In your program, you must use a switch statement instead of an if-else if statement. Use the standard 10-point grading scale shown in the previous problem.

Posted below is a picture of a data table and a diagram of an experiment. In the experiment you rolled a marble down a ruler ramp off the end of a coffee table to observe projectiles and conservation of energy. You do 3 trials for each initial height. Each height is measured in meters.
h= initial height of marble off of table
Y= height of table off floor
X= horizontal distance marble goes from edge of table to where it strikes the floor
a) use the table to find information you need to solve for theoretical range and % of error in measured range.

2. programable speed of a rover: . something that says that a rover is programmed via speed, that it doesn't matter if the weight of the rover is decreasing from time to time. something that says that if you programmed a rover to go 5kph it will remain 5kph even if you put something heavy on it.
You own a wheat warehouse with a capacity of 20,000bushels. At the beginning of month 1, you have 6,000 bushels of wheat. Each month, wheat can be bought and sold at theprice per 1000 bushels given in Table 46.The sequence of events during each month is as follows:a You observe your initial stock of wheat.b You can sell any amount of wheat up to your initialstock at the current month’s selling price.c You can buy (at the current month’s buying price) asmuch wheat as you want, subject to the warehouse sizelimitation.Your goal is to formulate an LP that can be used to determine how to maximize the profit earned over the next 10months

- Hi. I am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect. So far I have calculated and tried to input the following values: 0.0342 m3/s, 0.0358 m3/s, 0.04277 m3/s, and 0.0555 m3/s but it always keeps saying they are incorrect.

- Engineering Economy A company has determined the price and the monthly demand of its products are related by the equation D = √775 - p, where p is the price per unit in dollar and D, is the monthly demand. The associated fixed costs are $2,125 per month and the variable costs are $100/ unit. Use this information to answer the following: a)What is the optimal number of units that should be produced and sold each month? b) What is the maximum profit? c)Determine the value of D that represents the break-even point?arrow_forward71.7 is being marked wrong in McGraw Hill homework. I thought I had done it right with putting 86.03 but that is wrong also. I'm not trying to just find the answer, trying to find how to do this. Could there be a different number than 71.7? Where does the μk=0.20 come into the equation?arrow_forwardPlease double check before rejecting this question. If it needs to be rejected, please explain why as I cannot see how this is a breach of the honor code. This is a questions from the previous year's exam at my university in Engineering Science. I have submitted a solution given to us for study purposes as proof that I will not be graded on this assessment. In this solution, the formula (2gh)1/2 is used to find the solution, but I am on familliar with Bernoulli's Principle (P=1/2pv^2+pgh), and I was not able to find a solution using this. My solution incurred an error when I found that I had two unkown variables left that I could not break down in any meaningful way. (Velocity being the desired variable, Pressure being the problematic variable). Pressure = Force x Area, but I don't know enough about the dimensions of the tank or tap to be able to understand this. Thank you for your help.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_forwardPlease help Matlabarrow_forwardI am trying to practice this problem using a checker online, but everytime I recalculate my answer it always says it's incorrect.

- after solving, pls explain why u got the answer really need an explanation thank u so much pls explain in sentences. will ratearrow_forwardHi, I need help with the first part of the problem below because I'm very confused about how P1 and P2 should be calculated. If you look at my notes to solve the problem there is already a formula in place as I always thought the Patm should also be multiplied by the Area in the numerator, but it's not if I look at this specific tutorial solution given by my course but it's not explained why. I have done a while ago a very similar problem with using that formula in my notes and it gave me the right results, but it's not working for this one. Could you please help me understand why as I have a test coming soon?
