Physics lab problem

Name: Anonymous 2008-09-03 19:22

Hey /sci/, I'm having a problem understanding my physics lab. I don't mean for you guys to do my homework, but I do need help and my teacher is out of commission for a few weeks so I have no one else to ask.

"Consider the various combinations of force vectors studied in this experiment.

In the first combination, how can the two vectors F(1)-> and F(2)-> be combined to produce (i) a maximum and (ii) a minimum magnitude?"

Am I being asked to maximize the downwards force being applied to each vector, and then to minimize it? If so, isn't the answer just placing both as close to each other as possible to maximize it and placing them on opposite ends to minimize it?

It seems to be just adding the two vectors to maximize/minimize your magnitude, from what's there. Are both vectors applied at the same point? Perhaps some context could further illuminate things.

The magnitude of the sum of two vectors is maximized when they're pointing in the same direction and minimized when they're pointing in opposite directions.

Thanks a lot guys, that's what I thought

How the fuck can you add two vectors in different ways, if you change the direction they're pointing, they're different vectors.


Your question is shitty and ambiguous.

Vectors of unspecified direction but specified magnitude.

Oh man I just totally blew your mind didn't I?

Don't change these.
