Question

TASK: C programming Create a program in either visual Studios or an online compiler that will use the modern lift equation to calculate the average litt force of input values provided below. The modern lift formular L-a" I. - lift in Newtons air density in kg/m3 V = velocity in m/s 4 - Wing area in m CL = 2 x Pl x angel of the wing This formula is used to calculate the lift produced by airplane wings. You can find more info about this formula here: htts://wright.nasa.gov/airplane teq.html It is your job to create a program that finds the mean average lift of these sangles, you should also display the lift of each angle: (O",2,5,50", 15) These angles will be entered into the program by the user using the scanf() function Your program should however not accept angles greater than 45° or less than 0". If your program has a number outside of this range, it should ignore this cakulation from the final average but still calculate the average lift of the other angles entered The following values will be constants in your program: Air density = 1.225 kg/m Velocity = 50 m/s Wing Area 5m x 1mm Note: If only 4/5 of the entered angles are within the range desired, then you should only add the 4 angles within the range and divide by 4 instead of 5 to calculate the mean average. However, the lift of the 1 angle that is not included in the average is still calculated. Another Note: Make sure to use float variables in your program, where needed. The below is your expected output of your program: Enter angle 1: 0 The angle coefficient is - 0.000000 The lift of this angle is = 0.000000 N Enter angle 2: 2 The angle coefficient is = 12.568000 The lift of this angle is = 96223.750000 N

Answer 1

#include <stdio>

/* Constants */
float airDensity = 1.225;
float vel = 50;
int area = 5;
/* Global Variable */
int angles[5];
int count = 0;
float pi = 3.142;
float coefficient;
float liftAngle;
float sum = 0;
float meanAvg = 0;

/* Main Loop */

int main()
{
//printf("Calculating mean average of 5 lift angles \n");
  
for(int i = 1; i<=5; i++){
printf("\nEnter the angle %d : " , i);
int angle;
scanf("%d", ∠); // taking input of each angle
coefficient = 2*pi*angle; // formula of coefficient
printf("The angle coefficient is = %f ", coefficient);
liftAngle = coefficient*((airDensity*vel*vel)/2)*area; // formula of lift angle
printf("\nThe lift of this angle is = %f ", liftAngle);

if(angle <45>=0){ // apply condition as per the requirement and check the angle is in range or not

count++; // count of valid angles
sum+= liftAngle; // sum the valid angles
  
}
meanAvg = sum/count; // calculating mean Average
}
printf("\nThe average of the �ngles that were in range is %f", count, meanAvg);
return 0;
}

Enter the angle 1 : 0 The angle coefficient is = 0.000000 The lift of this angle is = 0.000000 Enter the angle 2 : 2 The angle coefficient is = 12.568000 The lift of this angle is = 96223.750000 Enter the angle 3 : 5 The angle coefficient is = 31.420000 The lift of this angle is = 240559.375000 Enter the angle 4 : 50 The angle coefficient is = 314.199982 The lift of this angle is = 2405593.500000 Enter the angle 5 : 15 The angle coefficient is = 94.260002 The lift of this angle is = 721678.125000 The average of the 4 angles that were in range is 264615.312500
