Answer: To calculate FL, we need to find the value of the variable "L" in the equation. We are given the following equations:
Ke/fa = 13/9
KI = 25
Let's use these equations to solve for L.
First, let's rearrange equation 1 to isolate "e" in terms of "f" and "a":
Ke/fa = 13/9
Ke = (13/9) * fa
e = (13/9) * fa / K
Next, let's use equation 2 to substitute the value of K:
e = (13/9) * fa / 25
Now, we have the expression for "e" in terms of "f" and "a."
The variable "L" is not explicitly given, so we'll assume that FL refers to "f times L." Let's represent that as "FL."
FL = f * L
Now, let's find the expression for "L" in terms of "f" and "a" using the value we found for "e":
L = FL / f
Substitute the expression for "e" into the equation for "L":
L = FL / f = ((13/9) * fa / 25) / f
Now, simplify the expression for "L":
L = (13/9) * fa / (25f)
L = (13/9) * a / 25
So, the value of FL is (13/9) times "a" divided by 25.
