Lets say you have a completely rigid blue-colored object shaped as shown below. The object had one wide protrusion on one side and four smaller protrusions on the other side. Everything is completely symmetric so that the weight would be evenly distributed. Let's say you press with 12 N of force...
I just have a basic physics question about bicycles that has been confusing me. Consider three situations. In the first situation a person, of mass m, is running down a street at constant velocity v1. In this case the person is converting energy stored in their body into translational kinetic...
So I'm still a little confused. I'm assuming that for a Villard cascade voltage multiplier that there is some formula that gives the output voltage given the input voltage, the capacitor's capacitance, and the number of stages. Also, I'm assuming there is some formula that gives the power output...
I want to build a safe Villard cascade voltage multiplier so that I can create sparks that I can touch without dying or being injured. Is it possible to do this? And if so how would you construct it (specifically what capacitors and rectifiers and power source would be used)?
My second question...
So I have a PhD in physics specializing in experimental soft matter physics/optics, and I have been unsuccessfully trying to get a job now for 9 months. I've been applying to engineering positions all of which I was very experienced in, but I can't even get a single interview (not even with a...
