Baluncore replied to the thread Curvature of the Horizon.Your elevator car is a transparent sphere, with your head at the centre. The sphere is marked with circles of negative latitude, from... -
Baluncore replied to the thread M 8.8 Off East Coast of Kamchatka.This was a deep earthquake, so there will be less tsunami wave amplitude than a shallow quake. It should have no effect on the Southern...

Baluncore replied to the thread Collection of Lame Jokes.It is not, that is a misquote. The love of money is the root of all evil. They ask for money in church, because they are trying to...

Baluncore replied to the thread Eliminating a differential of an e-rickshaw by using 2 motors..Assuming the motors are identical DC motors, wire them in series. The currents will then be the same, so the torques will be the same...
-
Baluncore replied to the thread Vector/Phasor Addition.I think the only advantage is that it avoids the one final evaluation of a square root, but accuracy there is not usually critical. The...
-
Baluncore replied to the thread Vector/Phasor Addition.It does make sense. Given a chain of added vectors, and knowing the direction of the total, all vectors making up the chain can be...
-
Baluncore replied to the thread Vector/Phasor Addition.The problem with the cosine and sine rule technique for vector arithmetic, is that there are too many opportunities to get a sign wrong...
-
Baluncore replied to the thread Vector/Phasor Addition.Inputs. V1 = 10 units at +15° from reference V2 = 70 units at +90° from reference Convert polar to rectangular. x1 = 10 * cos( 15° ) =...
-
Baluncore replied to the thread Vector/Phasor Addition.Yes, but tan-1(y/x) is Atan(y/x) and it gives you the slope of the line as an angle, not the direction of the vector, there is a...
-
Baluncore replied to the thread Vector/Phasor Addition.Be more specific. Which method, to do what? Summing vectors involves summing the x and y coordinates independently. That is done as if...

Baluncore reacted to DaveE's post in the thread Beauty of old electrical and measuring things, etc. with
Like.
Perhaps the most risqué HP ad. Circa 1972. I recall this from a poster in the hallway of the Caltech EE building when I was an... -
Baluncore replied to the thread Vector/Phasor Addition.I don't believe corrective real powers are the way to go, even if you can make it work. Real powers of real numbers involve a Log(), a...

Baluncore reacted to Rotem Tsafrir's post in the thread Weird near-field phenomenon I get in my EM simulation with Like.
That’s seems like a great explanation. Thanks a lot!

Baluncore replied to the thread Weird near-field phenomenon I get in my EM simulation.The group velocity propagates at the speed of light. The phase velocity moves at between the speed of light and infinity. Consider a...

Baluncore reacted to Swamp Thing's post in the thread Weird near-field phenomenon I get in my EM simulation with Like.
Could it be something analogous to the "superliminal scissors" thing where the point of intersection moves faster than light? Say we...
