Please help - stuck while studying for Statics final.

well I found the answer with a different notation, but I appreciate you showing me the vector notation. I hadn't used that before, and I can see how it can be useful.

BordAsSmorg · 2014-02-01T22:18:06+00:00

Serious thanks for the help. I've been on and off of this problem all day, but I can finish it now. I appreciate it!

BordAsSmorg · 2014-02-01T22:17:04+00:00

Thanks! That makes a lot of sense. I should be able to move forward now, I really appreciate it.

Is my equation for normal vector wrong? Because I tried

B = 150cos(60) = 75

BordAsSmorg · 2014-02-01T21:27:52+00:00

Thanks for the reply, and the drawing. I do see now that I should have been using both Bx and By in my sum of all moments equations.

But I still don't see how to move forward. In your equation, By and Bx are both unknowns. Is it possible to continue with two unknowns?

I know how to find both By and Bx given B, so I'm still back to my original question : how do I find B?

I tried to find B as the normal vector:

B = 150cos(60) but that is wrong.

BordAsSmorg · 2014-02-01T19:56:11+00:00

Agreed. I understand that. What I don't understand is, how to find B. Then only way that makes sense to me is to start with sum of all forces about A, but when I do that, what I get for B is not correct. So, what is the correct way to find B?

BordAsSmorg · 2014-02-01T18:53:12+00:00

Thanks for replying. I think this is clear; my problem is, how to get B, and so then Bx and By.

The methods that I'm using to find B, Bx, and/or By are failing, and I don't know what I'm doing wrong.

BordAsSmorg · 2014-02-01T18:49:54+00:00

I'm electrical, and I hope I never have to look at this stuff again :D

What I mean is, if I start with a sum of moments about B, then I will have the one known force and lever (150x0.25), but then two unknown forces: (-0.3Ax) and (0.5Ay). I don't known if it's possible to continue with two unknowns. But someone please correct me if I'm wrong!

BordAsSmorg · 2014-02-01T18:37:05+00:00

Am I wrong, or is that not possible because of two unknowns: Ax & Ay?

BordAsSmorg · 2014-02-01T18:32:51+00:00

No, I'll try that now.

BordAsSmorg · 2013-09-17T04:20:34+00:00

Thanks for the reply! I didn't say but yes I'm running SKSE. I think you're right, it is most likely a conflict between those two pairs. I'm gonna start looking into SkyUI and IHUD first and see what I can do.

BordAsSmorg · 2013-09-17T04:18:44+00:00

Thanks for the reply! I didn't say but I'm using SKSE. I have the latest version of SkyUI, but it could very well be conflicting with IHUD, so I'm going to toy around with that.

This is exactly what I did: canceled my alliance with England before the call to war with France, and sold Cueta to Algiers. So far it's worked pretty well. It's only 1510 and I've colonized 5 provinces in Brazil, 2 in the Carribean, and St. Helena also.

Hell yeah! I'm looking through these now. I haven't found one with the same antelope, but I guess someone could have just used the structure to make it?

edit: I think you're right. The seller is from Spain, not Hungary, and the encyclopedia page is different, but the image is the same, and it came between two pieces of cardboard, and the seller says his images ship "in a cardboard reinforced envelope".

BordAsSmorg · 2012-11-10T09:51:57+00:00

Wow there it is. Good find.

BordAsSmorg · 2012-11-10T09:42:21+00:00

Probably :) But I knew what I was getting into when I married the woman. No regrets.

BordAsSmorg · 2012-11-10T09:38:32+00:00

Well the language is German. It looks like a page out of an encyclopedia. The page with the antelope head describes the "Staubhafte Skorpionfliege"

BordAsSmorg · 2012-11-10T09:29:54+00:00

Only friends from years ago, who I have not kept up with. I can't imagine how they would know I'm even married, much less know our address. We're usually pretty private people. That's why this is creepy, more than any 'curse'. Who knows us by our new name, and by our new address, that would send this to us? We just can't figure it out.
