    [ANSYS] Simulation of Permanent Magnets

    I have a project where I need to simulate the magnetic forces with ANSYS. I'm and intermediate ANSYS user but I have really only worked with APDL, and if possible I would like to do it in the GUI. So my problem is that I have only ever done structural and thermal models in ANSYS. I am...

    How do I solve for H in matlab?

    I need help implementing this bit of code into matlab. I have a known matrix lest call it Z. and I have another unknown matrix called H. The matrices are related by the following relationship. Z = HTH How do I solve for H in matlab? If it is relevant Z is a make up of other known matrices and...

    Broken Geometry (Cylindar) Fit Inside a Box

    I have a pretty simple math problem that has been giving me the biggest headache. So what I need to do is optimize the space that I am using. Thus I have a piece that can be seen like a 20 inch in diameter cylinder that is 6 inches tall. I would like to be able to break it into as few pieces as...

    How to Write MATLAB Code for Control Systems with Variable K?

    I have a given system and I need to A) determine the transfer function B) find the values of K form Routh-Hurwitz C) Determine the values of K for the stable region D) Create the simulink model. I want to know how to write my MATLAB code so that I can solve what I need to. I DO NOT want...

    Engineering Time variant RC and RL circuits

    Ok so I have some topic overview questions. I think I am on the right track but would like to make sure I am thinking about this the correct way. When I say time variant I simply mean there is a simple switch in the circuit. This is link to a were I found my supplemental material and it has...

    Convert device from AC to DC powered

    Oh I should also explain how the blue and red wires go. The red goes to one of the outlet prongs and the blue comes from an outlet prong and goes to a inlet prong for the outlet. If you need more information let me know. I am sorry this is getting like 20 questions but I have not a clue what...

    Convert device from AC to DC powered

    Here are the last two. Pic5 and pic6 I have no idea are what the red thing and the capacitors and resistors are used for. Thanks for the help.

    Convert device from AC to DC powered

    I am not sure what goes through the wires I am disconnecting but they are about 22-gague wires. They go into a molex plug and then into a circuit board. The board is plugged into the wall (AC) however it is converted to DC I think. So the main lines I want to disconnect are DC. Here are...

    Convert device from AC to DC powered

    I am not familiar with those. The reason I went to the wireless outlets is because I need them to be cheap (under $5) because I am making a number of them. And secondly I need them to be wireless. I need to be able to send a signal and activate the on/off. I am also looking to possibly make them...

    Convert device from AC to DC powered

    I just bout some wireless controlled wireless outlets. Theses are what I bought: http://www.menards.com/main/electrical/safety-security/timers/indoor-wireless-remote-outlets-3-pack/p-1477247.htm I want change how they draw power and the functionality. I am new to circuits and have a novice...

    Signal and Time Displays in Everyday Devices

    Question: What signal (voltage or otherwise) vs time displays do you have in your house? Answer? I am a little confused as to what exactly this question is asking. My initial suspicions say that a TV because they receive a signal over time and display that as picture on the screen. Also I...

    Capacitors and related Voltages.

    Homework Statement 1) A capacitor plate holds a given charge Q. Why is the magnitude of the plate voltage small when a grounded plate is near, but large (for the same Q) when it is alone? 2) If the charge Q on a capacitor is doubled, what is the change in the voltage one measures on the...
