Again, sorry for making alot of threads, I just found this forum and I have many questions. I am attempting to model a simple 2D surface in ANSYS that is subjected to a load in the 3rd dimension. My surface is a table top, in the X-Y plane. I have modeled it in 2D, and will give it a "simulated...

Again, sorry for making alot of threads, I just found this forum and I have many questions. I have a question about finding books where is defined heat conduction threw construction materials. It's going to be useful to me if you tell me where can i find some experimental data or theoretical...

Again, sorry for making alot of threads, I just found this forum and I have many questions. I am planning to build a solar cooker that van cook food as fast and hot as possible. I was wondering what is the best reflective material for concentrating the sun's rays into a single point. A...

Again, sorry for making alot of threads, I just found this forum and I have many questions. Hey everybody I have a question and maybe somebody out there can help me out. Can anybody help in understanding Nyquist plot for type 2 system K/[(s)2(1+sT)] Thanks...

Again, sorry for making alot of threads, I just found this forum and I have many questions. A while ago I built a pc board that serves as a 3 channel SS relay. The output thyristors are 25A. This circuit uses a zero cross opto coupler to fire the thyristor and turn it off (DigiKey MOC3042)...

Again, sorry for making alot of threads, I just found this forum and I have many questions. When p and n meet they form a junction. Shortly after a depletion zone is formed. I have a question about this forming. Probably the obvious answer. Near the junction, electrons from n-type crossover...

Again, sorry for making alot of threads, I just found this forum and I have many questions. I am working with flexible electrostatic adhesive pads. These are similar in many ways to a normal adhesive tape in but the adhesion can be turned on and off electrically. Like many adhesives they are...

hi all.. Again, sorry for making alot of threads, I just found this forum and I have many questions. i facing problem to get a good contour..because the scale at fringe levels so big. for example: level 8 = 1.224e+037 level 9 = 6.122e+036 level 10 = 0 i have 4500 element that the value...

Hey guys sorry for making threads so fast, I just found this forum and I have alot of questions. Hi, I need to calculate the stationary velocity profile for the Navier Stokes equations in cylindrical coordinates. Can anyone help? Thanks, ____________________________________ Φωτοβολταικα

Just a short question. As part of a dyno project, I am coupling two dc motors together with a timing belt. To allow the same rig to be used for different test motors, I am considering mounting this (test) motor on a table, which can be positioned in two directions on leadscrews. This would...
