Hmmm...on a related note if I knew the angular acceleration of the helicopter how can I compute its moment of inertia to obtain the net torque on the copter? I heard that for shapes with simple objects, the moment of inertia can be found by considering its dimensions?

I'm working on a Paper Helicopter Experiment in school where I'm looking at the deflection angle of the rotors versus the rotational velocity of the copter. I'm having difficulty forming a relationship between the deflection angle and the torque that the helicopter experiences But how exactly...

Hmmm unless i change the mass of the handle by say, sticking blu tak on to it?

Hmm i understand that the lower frequency is produced when the handle coincides with the antinode of the standing wave produced hence increasing the mass vibrating and reducing the frequency. But at most, the very same coffee mug will only produce 2 different resonant frequencies right? If I hit...

Hmmm this experiment is exactly the kind of thing I'm looking for and plus since its got two resonant frequencies I can even possibly explore the relationship between the two and any independent variable I'm changing. Thanks for the suggestion :D problem is now though I have to identify...

Hi all. I am planning to do an IB extended essay on physics but unfortunately I am having some problems with coming up with a good research question that will allow me to conduct an experiment with high school equipment but involve theory and maths at the IB level. Originally, I intended to do...
