Hello, I have two vectors, the angle between them is dynamic and constantly changing. I have found a way to calculate the angle between these two vectors. But this angle is always a positive number even if i am looking left or right. How can i get context(wether vector DC,DB,DE,DF according to...

Haha that was a rhetorical length. My real length will be about .4 meters. And my displacement will probably be .5 or .6. And there is an axel through the other end. It is bent over a triangle shaped crossbeam.

I am calculating the initial velocity of a released pvc pipe after it has been bent. I would like to know if i have this correct. Potential energy = Kmgh; I have my mg and it is 50N, so PE = k*50*h; I have been told that k is the spring constant of my bent pvc pipe. Therefore since I have...

Okay, Say the wench has a spring scale attached to it. The spring scale says its pulling at 50 Newtons right now. How do i get the force applied when i release the arm from the wench?

any ideas on what i need to supply?

I wish i could, But I am not for sure what kind of info or how to calculate it.

How can i calculate the initial force of this mechanism?https://dl.dropboxusercontent.com/u/3625527/4/Demo.jpg I don't even know where to begin working on this part of my problem.

on the issue of sonar. it seems very intruiging but there may be a few probelems i need the tracker to be a small bar roughly 1"x4" and can sonar be used to track a single body part?

is it possible to calculate the location of say my right hand and track its motion without using any cameras.(using radio triangulation,accelerometer,etc..) i would like to have some sort of ground sensor. and i only want to track that one object not several, i would like to know the distance...

well then i have another question, I've been trying to find a way to track the location of something that is > 2ft away < 10 ft away. is there any way to do this, i have looked at radio triangulation, light, etc but i cannot find anything.

Is it possible to have one accelerometer placed at ground level and one in your hand. and without either moving use the difference in Gravity's pull to calculate distance or rather height of the second accelerometer?
