MATLAB project : To calculate the Drag force experienced by the cyclist and plot the various graphs.

1.AIM :  To calculate the drag force experienced by the cyclist. To plot a graph between Velocity of cycle(v) to the drag experienced by the cyclist (Fd). To plot a graph between Drag Coefficient ( C d ) and Drag force( F d ).   2.Governoring Equation   F d =  0.5 * C d * v * v *𝞀   Where, F d =  Drag force  C d =  Coefficient of drag v  = Velocity of the cyclist 𝞀 = Density of the air   3.Objective of the project   To write  a MATLAB code that will help visualise the graph as mentioned above.   4.Procedure   When a cyclist moves in a direction it experiences a resistive or friction force. In fact, there are a lot of forces which may act on the cyclist during his run, like friction forces between road and tyres of the bicycle,force of friction between chain and sprocket etc. But for our consideration we are taking into account the force which is experienced by the cyclist due to air,which ...
