1. AIM:-Program to calculate drag force against a Cyclist.

2. GOVERNING EQUATION:-

•             <math>Fd=rho∗v2∗a∗cd/2F_d=rho*v^2*a*c_d/</math>2Fd​=rho∗v2∗a∗cd​/2
•         Where         <math>FdF_d</math>Fd​ =Drag force
•                               units:-<math>NN</math>N
  
•                               rho=density of medium through which cyclist is travelling(air)
•                             units:-<math>kg/m3kg/m^3</math> kg/m3   
•                             a=frontal area      
•                              units:-  <math>m2m^2</math>m 2
•                             v=velocity with which cyclist moves
•                             units:- <math>m/sm/s</math>m /s        
•                             <math>cdc_d</math>cd​    
  =drag coefficient

3. OBJECTIVE OF THE PROJECT:-

1.  To calculate the drag force.
2.  To  plot Velocity vs Drag force.
3.   To  plot Drag Co-efficient vs Drag force.

4. CODE :-

                CODE FOR  VARIATION OF VELOCITY AND DRAG FORCE

    OUTPUT:-

5. EXPLANATION OF THE CODE:

1. First initialize the values of  rho,frontal area,c_d,varying velocity.
2. Substitute those values in the force drag equation to calculate drag force.
3. Then plot  a graph between velocity and drag force.
4. For second case  initialize the values of  rho,frontal area, varying c_d, velocity.
5. Substitute those values in the force drag equation to calculate drag force.
6. Then plot  a graph between c_D and drag force.

6.CONCLUSION:-

1. Calculated drag force with varying velocity and c_d.
2. Plotted the graphs between velocity vs drag force and c_d vs drag force.
