Homework Statement click on link for picture of problem http://i21.photobucket.com/albums/b300/DrGame/morhs.jpg The Attempt at a Solution Well I'm just really confused because you have two torques, and you can't draw morh's circle that way.. I've tried about 3 hours of various things...

She was claiming to feel sick when she discovered the blood coming out too, just wondering if that's a sign of spotting

After talking more about it, this happened two days ago.. nothing much was thought of it, apparently she actually only bleed for half a day (from lunch until bed, and woke up with nothing). This could mean she was spotting possibly correct? She said she has been feeling different.. her mind...

I don't know where else to ask something like this, but a friend of mine had her period and lasted a day and a half.. and is worried that she could be pregnant... but that's not possible if her eggs dropped because she started her period right?

I'm wondering if anyone is willing to share some comparison numbers between any aluminum's hardness value and its impact resistance value. A friend and I are disagreeing on something, I think the harder the treatment is, the more brittle it becomes. He doesn't think so.

did you find a program to do it? and LT stands for Laplas Transform

Homework Statement Find the LT of this... \frac{s^3 - 2s^2 - 6s - 6}{s^4 + 4s^3 + 24s^2 + 40s + 100} Apparently this question is solvable.. however.. the first step is nasty, I have no idea how to factor this... the ways I know won't work? Can someone help me out with factoring out the bottom?

no idea? I take it your saying its just \frac{C}{4^2} Edit: oh nvm, you just ignore the part after B.. then add it in later...

if you have \frac{3s + 1}{(s+2)^2 + 4^2} does it become... 3s + 1 = \frac{A}{(s+2)} + \frac{B}{(s+2)^2} + \frac{C}{4} + \frac{D}{4^2} or... 3s + 1 = \frac{A}{(s+2)} + \frac{B}{(s+2)^2} + \frac{C}{4^2}

Is there a free Laplas Transform Calculator out there on the web? Perferably a java script. But aslong as there is an online calculator that can give a final answer, it doesn't matter. Thanks.

The following is an image of 1018 steel I annealed, image size is 100x zoom Just wondering what the darker regions are... perlite? http://i21.photobucket.com/albums/b300/DrGame/181879b.jpg

I know annealing makes a material more ductile, but what are the differences in the structuer of the material? I have a picture I took of 1018 and 1040 untreated... if you know the difference, think you can point them out? I'm not looking for differences in any specific material I just have...

somebody please?

Homework Statement A half wave rectifier is supplying a load current of 100 mA. The input frequency is 60 Hz. Find the capacitor value required to limit the ripple ot 160 mVpp. Really... I can solve this I'm sure... But I'm wondering what formula I need to use... I've never been shown one...

you just have to find your re crystalization temperature
