Your free body diagram looks right. Now take a moment around G to find what member DE is. Next, sum the forces in x and y to find DG and GH. Was I helpful to you with this? I really struggled with trusses in statics and now have a really good understanding of how to solve these problems.

Just making sure of this, but... we need to make sure that the multiplicity of the eigenvalue (if only one) equals n of I_n. I'm doing some late-night studying, catching up so hopefully I can pass my exam on Wednesday. I hope I can learn to like linear algebra after this class is over. I'm...

Thank you for your detailed reply. This is helping a lot.

Nevermind, I feel dumb for posting the question! I found some examples :-)

This is a general question because I don't seem to be getting a straight answer from my textbook. I know how to find eigenvalues/vectors, but finding IF an eigenbasis exists is what is throwing me off. Can someone give me an example of, say, a 3x3 matrix and go through the procedure of...

I am fine with integration, but I'd like to really understand how to do these problems before using calculus. Thank you again. I really appreciate your help :-)

Thank you thank you thank you. You really helped me to understand this problem and I now feel comfortable if I write a moment wrong. For some reason, I felt comfortable with drawing forces in the wrong direction but not moments when we got to chapter 7. I have the 12th edition of Hibbeler and...

Here is what I have so far: http://www.scribd.com/doc/82663003

Okay I've sort of figured it out. Hopefully, I'm getting somewhere with this: ABxCD, and then make this a unit vector. Then dot this unit vector with vector AC. The question asks "what is the maximum height z can be...". The distance from the center to the radius of the two conduits when...

Homework Statement http://www.scribd.com/doc/82645310 In Figure 3-31, the lines AB and CD are the center lines of two conduits 1 ft. and 2 ft. in diameter respectively. Determine the maximum value of z so that the two may pass without interference. Conduit CD must pass under AB...

Okay, never mind guys! I guess staring at something long enough makes me understand it.

Yep, a scalar dotted with a vector is undefined. Finally, something I can answer! :-)
