Dynamics of Machine Course Help

Hi All,

I was wondering if anyone could post some videos or some websites where I can read about Dynamics required for Mechanical Engineering i.e. related to vectors , how to add vectors , how to find the resultant. I searched YouTube but I am not really getting any good responses.

I am a third year student and I don't really know Vectors that well and I find no way in my books to brush up on that, for e.g. I don't remember the parallelogram vector law and triangular one and its confusing me during class and I keep cursing my self for skipping that part in Physics when I was in school.

I hope you get the idea.

Thanks

If your looking to brush up on vectors you should review Statics first since Dynamics will more likely confuse the situations since you also have to deal with how position relates to velocity, and how velocity relates to acceleration, instead of just dealing with direction.

Either way the easiest way to think of vectors is as a trig or geometry problem where you have so much force, velocity, acceleration going in the x, y, and z direction, where the magnitude of these properties would equal the following:

magnitude = sqrt (x2+y2+z2)

Anyways, some sites that might help with dynamics are the following.
