I'm working on a problem but I've hit a road block..
Then the cross section of the piece is here:
The first part of the problem is to determine Iy, Iz, and Iyz of the member.. I found the y value of the centroid to be 2.8587" and the z value of the centroid to be 1.0734" using the...
I'm working on a problem for my diffEQ's class. It reads:
For each of the given initial value problems, what is the region where the existence and uniqueness of the solution is guaranteed? Is it all t, or t > -3, or a neighborhood of t = 1?
a) x'' = t x x' + sin(t)
b) x'' = tx + 2x' +...
Hey guys, I'm working on a project involving a DC motor. I'm in school for mechanical engineering.. Electrical problems haven't really interested me so this is the first I've ever really looked into it apart from studying basic circuits in a physics course last year. Anywho, the project:
