how do I solve this problem in matlab? thanks for help!
The lift equation is given as (1) pv AC where L is the lift force, p is the air density, v is the true airspeed, A is the planform area (the projected area) of the wing, and CL is the lift coefficient. The draft equation is similarly given as (2) pv AC where D is the drag force, CD is the coefficient of drag, and p, v and A have the same meaning as they had in Eqtn (1). CL and CD are dependent on many factors such as the body's shape, Mach number (the ratio of the speed of an object moving through a fluid and the local speed of sound) Reynolds number (the ratio of inertial forces to viscous forces and the direction of the flow Consider an aircraft with a planform area of A 438.6 m a lift coefficient estimated to be CL 2.1 (dimensionless), a drag coefficient estimated to be CD 0.24 (dimensionless), and which is traveling through air with a density of 1.232 kg/m3. You want to know the lift and drag forces for 14 linearly spaced true air speeds between 25 m/s and 350 m/s. Use a for loop to create a cell array where each cell contains values corresponding to each true air speed. Each cell must contain a structure array called forces that has a field called lift and a field called drag; in other words, you will place a structure array inside of a cell array. Outside of the loop, print the lift and drag forces (each with a label and a unit that correspond to the true airspeed of 350 m/s Hints: (1) Consider what variable the fields for your structure array actually belong to Ci.e multiple indexing layers). (2) The command end can be used to call the last element ofa cell array. (3) The final lift and drag forces are 69,503,187.6 N and 7,943,221.44 N, respectivelyExplanation / Answer
here uploaded question is not uploaded corrected but i am here explaining the matlab to solve a engineering problem... % PROGRAM to obtain ROOT LOCUS PLOT USING SS MODEL
clc;clear;close all;
A=[-2,-1;3 0];
B=[1;2];
C=[0;1];
D=[0];
RLOCUS(A,B,C,D).
%plot reset locus
[n,d]=ss2tf(A,B,C,D); %Print transfer function
disp('the eq transfer function is:');
printsys(n,d)
