I need some free software that will allow me to design something like a case (that will house a small circuit board/clock) Any software that will allow me to do that?

Homework Statement Here is the problem: http://img507.imageshack.us/img507/6488/unled2b.jpg What is the open circuit output voltage, Vout? Estimate the short circuit output current Can someone explain to me how to do these. Homework Equations Honestly... no idea. I know V=IR and all that...

Homework Statement I need help with this: http://img716.imageshack.us/img716/3262/unledewk.jpg I know that I need to create an extended free body diagram and I understand how to get all the equations from the diagram. BUT I don't know what to do when it comes time to use torque and find...

So does that mean I find v by means of conservation of momentum, and then use omega = v / r to find the answer? The reason I'm confused is because at the note at the bottom of the question, it says treat the door as a rod rotating about its end, which is a hint to use Inertia = (1/3)ML^2...

Homework Statement I need help with this question: http://img804.imageshack.us/img804/2278/unledsbg.jpg For a, I got omega = 18.63 rad/s by using methods of conservation of energy. Can someone tell me if I did this right? If not, please help me out! To be honest, I thought I had to use...

Homework Statement [PLAIN]http://img16.imageshack.us/img16/7396/oscf.jpg What is the RMS voltage of the top wave? Homework Equations RMS... root mean square The Attempt at a Solution If I'm right, the peak voltage is 1 V (gotten from 2 * 500mV). Square of 1 is 1. And there are 4...
