A dynamics question

Say we are swinging a rope in a circle (vertically, so there is gravity) with a mass on the end. I'm having trouble with the free body diagram that would be associated with this. An example from an old exam I was looking at required the drawing of the positions at the top and at the bottom. Which wa...

Re: Help with shear force and bending moment

It's a statics course, I'm a first year so it's general. Thanks for the help, I think I can do these now, which is good as the test is coming up.

Help with shear force and bending moment

This is off an old exam that I am studying for Statics. The problem is to determine expressions for shear force and bending moment as a function of x between B and C I've gotten to this point so far: V=4kN + 3kN/m(2-x) However, that doesn't seem right as I think I should somehow be including the rea...

Re: Derivatives with exponents as variables

Thank you very much! It makes sense now. I liked the most your explanation of that rule (pretending the base is constant summed with pretending the base is constant).

Derivatives with exponents as variables

These ones are pretty simple, but I can't find the rules for them. They are the ones that involve variables in the power position. d sin(x)^x = e^(x ln(sinx)) (ln(sinx))xcosx /sinx I'm pretty sure that that's wrong. dx d 10^(sinx) = 10^(sinx) ln(10) cosx Again, I think I missed the answer. dx If any...

Fun with Moments

I have to find the moment about a point A. I'll draw a picture: fun with moments.jpg The positive and negative signs are just how I differentiate between cw and ccw. b is the point 1.8 m over and .3 m down from A. Using moment couples gets me the right answer (9), but we are supposed to sum it about...

Re: The U shaped things

That is probably it. The answer to my previous question is pretty simple then. If A belongs to both sets, the intersection must contain the point. Does that make any sense?

So what if it's backwards? Can I put this in context? At the risk of having you do my homework, one of the questions says

Really? I couldn't disagree more. Ender's Game and Speaker are probably my favorite books, but I didn't like the Shadow series at all. I stopped about a third of the way through Puppets . To me, it just felt like he was trying appeal to all the readers who liked Ender's Game but not his other books.
