Wind Tunnel Creation +more then 3 speeds

AI Thread Summary
To create a wind tunnel capable of testing an airfoil's lift at more than three speeds, a continuously-variable speed fan is recommended. Utilizing a PWM drive on a DC electric motor can achieve this variability. The discussion also suggests considering the types of fans available and the possibility of constructing a custom fan. Exploring these options will enhance the wind tunnel's effectiveness for the experiment. Implementing these suggestions will help meet the requirements for a comprehensive EEI.

I am making a wind tunnel to test the lift of an airfoil when chaning the variables of angle of attack and air velocity. For a good EEI I need more then 3 speeds. However, all the people I know only have 3 speed fans, I don't know how to get more speeds as the wind tunnel gets built around the fan. Any ideas??

You should be able to make a continuously-variable speed fan by using PWM drive on a DC electric motor. What kind of fans do you have to choose from? Can you make your own?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
