Calculating Wing Lift with a DIY Scale and Air Supply

AI Thread Summary
A DIY setup using a scale and air supply was created to measure wing lift, resulting in a negative value on the scale due to lift forces. To accurately calculate lift, the wind must be perpendicular to the scale's measurement axis, and any wind affecting the scale must be accounted for. The measurement process requires ensuring parallel wind streamlines for accurate results. Additionally, lift measurements can be influenced by turbulence levels. Understanding these factors is crucial for precise lift calculations.

Hi!
I have attached a small sheet of wood to a stand and then all of it to a scale. After that with a air supply I've made wind go through the "wing". Due to lift, the scale showed up a negative value. Knowing that value, is it possible to calculate the lift of the wing?
Thank you

How would you define lift? And how does what you are measuring differ from that?
 
The wind must be perpendicular to the scale's measurement axis, and any wind impinging on the weighing platform must be subtracted out. The trick is getting parallel wind streamlines. Also, lift will vary with the amount of turbulence.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
