Question
1. When used in the fprintf command, the In is used to add a space between any two characters B) add a line space (enter key C) place a number into the comment D) clear the comment 2. The str2num command A) converts a number to string converts string to a number C) concatenates numbers and strings D) concatenates strings 3. To solve a set of eqns 2x+3 y=53x+15y-8, the correct Matlab input is 2x+39:5; 3x+15 g-8 A) 123;3 15]/[5:8] (B) 12 3:3 15] 115:8] (C) [2 3:3 15] / [5 8] (D) [2 3:3 15] [5 8] 4. Write a computer code that takes as input the inclination angle 0, box weight W and coefficient of function static and as output: i)- Normal force and maximum friction force ii)- Find the force P parallel to the plane (Figure 1) necessary for motion impends up Test your code for: 0.30, w : 2001b6-30 0.20, w-300lb, -600 For = 0.30, w-200lb. Plot the variations of P for angle range [0-901 5. Determine the moment of force about the point where a bracket is attached to a wall. The bracket is shown in figure It extends 10 inches out from the wall and 5 inches up. A force of 35 lbf is applied to the bracket at an angle of 55 from the vertical. The answer should be inft-lbf, so you need to do some conversions of units 6. Calculate three new vectors for each of the vertical (v1, v2, v3) and horizontal (h1, h2, h3) distances traveled, assuming launch angles of pi/2. pi/4, and pi/6. In a new figure window, graph horizontal distance on the x-axis and vertical distance on the y-axis, for all three cases by making one line solid, one dashed, and one dotted. Do not forget to add a legend to identify which line is which For plotting, you need to create a matrix theta of three angles,mi/2,/4, and /6. Use the meshgrid function to create a mesh of theta and the time vector (t). Then use the two new meshed variables you create to recalculate vertical distance (v) and horizontal distance (h) traveled. Each of your results should be a matrix 200 x 3. Use the plot command to plot h on the x-axis and v on the y-axis.Explanation / Answer
1. It goes to the new line ie add a line space( enter key) in Matlab.answer is B
