Question
An ideal glider has drag characteristics given by0D D DiC C C= + , where2D LiC KC=is the induced drag coefficient,LC is the lift coefficient, and K is aconstant. For maximum range of the glider, the ratio0D DiC C is(A) 1(B)13(C) 3(D)32
Solution
To find the ratio 0D DiC C for maximum range of the glider, we need to determine the value of D and DiC C separately.
Given the drag characteristics equation 0D D DiC C= + , we can rewrite it as 0D DiC C= -D.
To maximize the range, we want to minimize the drag. Since D is a positive value, the minimum value of D would be 0. Therefore, the minimum value of 0D DiC C would also be 0.
Now, let's consider the given options: (A) 1, (B) 13, (C) 3, and (D) 32.
Since we want to minimize the ratio 0D DiC C, the correct answer would be the option with the smallest value. In this case, the answer is (A) 1.
Therefore, the ratio 0D DiC C for maximum range of the glider is 1.
