I used the tangent-chord theorem to get the length of the chord. Since 2 tangent lines created the chord, it formed a triangle. The chord as the base and the radius as the legs. As shown at the attached picture. I used sine(45) to get the value of h. Sine 45 × 2 =h h = 1.41 r - h = 2 - 1.41 =...

Homework Statement For monoplane of Clark Y wing, 36-feet by 6-feet, with 3.8 sq ft. equivalent flat plate area, what should be the airspeed for minimum Horsepower when fuel has been burned so that the total weight is 1800 lb? Homework Equations Wing Area = 36 x 6 = 216 Weight = Lift Weight =...

It seems that the given data about fuselage was at the problem for confusion. Thanks a lot sir! :)

Okay. Thanks for the information :) Hmm, one more thing. Aspect ratio = wing span / chord or Aspect ratio = wing span ^2 / wing area Which do I need to use in terms of exact computation? Because using both computation has a minimal difference on Drag. But for the computation of Coefficient of...

Wow! Thanks for that! I got it. I was confused for the usage of the given data about the fuselage. Anyway, I used 3.82 instead of 4 for the tip of the chord. Because of the tangential line. Is that okay? But the area of the circle will also change. Do I need to stick with 4ft tip? Here is my...

But, on the tapered, there's no given data for span :(

Hmm.. Since, the tangent line and Radius is perpendicular, then it creates a 90degrees. The other side is also 90degrees, would it be right if I use 45degrees for the chord line and the radius? :)

Di = [(Coefficient of lift)^2 (density at SSLC/2) (span) (velocity in ft/s)^2] / (pi x AR) Wherein AR = b/c For tapered wing, (Root chord + tip chord) / 2 I'm having a hard time to calculate for the tip chord.[/SUB][/SUB]

Can you give me hints on how can I relate the length of the tangent line to the chord? Pleaseee. Thank you :)

Hi, I'm here again. I have been able to solve the problem by using AutoCAD. I also searched for computations and calculations of the chord created by the tangential lines, unfortunately, i haven't seen any. Please help me to solve the chord at the tip :(

From there, can I use pythagorean theorem to solve the value of the tangential line? :)

Sorry about the template.Homework Statement Problem statement: [/B] Find the value of the chord (blue line) and at the same time the value of the tangential line. Given data: Red line = 6 Green Line = 3 Radius of the Circle = 2 Homework Equations I don't know any equations that can solve...

Homework Statement Attached here is a diagram. My questions are, how to compute for the value of the chord? How to compute for the value of the tangential line? Please help.. Thank you in advance.

Thanks a lot! I got the answer! :)

I'm still confused. Am I doing it right? Manually, how can compute for it. Attached here is the illustration of the given data. Hoping for your kind clarifications.. Thank you..
