Shorter version; I choose household bulbs because they are so common; take a 100 watt bulb and "install" it; P1 = 100 watts Now take a 150 watt bulb and "install" it; P2 = 150 watts. Now put them in series, and the total power of the bulbs is NOT P1 + P2 It's something LESS. LarryR

I don't claim to have THE answer, but have ideas. However the "answer" of "two bulbs having power of P1 and P2, connect them in series and what is the new power"? and the answer being the same as what was GIVEN, doesn't seem to be a "problem" at all..... There was no "homework" involved...

I apologize if I led anybody to believe thatthe original post STATED househld bulbs; I agree, there is NOTHING in that original post that says "household" bulbs, but there is nothing in MY post that says the original post MEANT or STATED household bulbs either; it was an example of "power" is...

I didn't do your math, but I agree that the power of each bulb does NOT stay the same as it was when installed in parallel. Assumptions? There are times for valid assumptions. When you buy a bulb for you home, they list the "power" on the box; example 100 watts. Now that ASSUMES that...

It's way past 2am my time; got to be short w/o giving answer. First, I don't see anybody discussing I sub 1 [amperage of first bulb], then I sub 2 [amperage of second bulb] and then of course when putting them in series, I sub 3 [same amps going thru both]. Then as to "assumptions", say they...

Please realize, everybody, that I have not reached "amateur" status, I'm probably less than a "beginner", but I'm not CONVINCED [who am I, LOTS of people are far more intelligent than me, but...] that it IS gyroscopic effect that keeps the bicycle upright, I think that because of the "rake" and...

OK, no takers; so then perhaps you can help me get STARTED; how about this question. On a gyroscope, we have the weight of the spinning wheel aiming downwards, P force UPWARDS happening by the bicycle fork? then you have L which I believe is Angular Momentum, but it appears to be a vector...

Homework Statement Bicycle traveling 20 ft/sec. Moment of Inertia of the front wheel is 0.25 slug*ft^2. Wheel radius is 15 inches. With what angular velocity must the front wheel be turned about a vertical axis to counteract the capsizing torque due to a 120 pound person being 1 inch...

qqqqqqqqqqqq For a very SHORT time indeed; yes, but the normal force you refer to is for, as you say, a "fraction of a second", so the moment the dia stops changing, now we don't HAVE that "additional normal force", as the rising axle has STOPPED accelerating upwards; no acceleration upwards...

Sounds like I'm a "non-physicist" in this response, toooooo, but your "because the electrons in orbit around the nucleus of atoms will repel each other." sounds more like a philosophical question to me.... ummmmmmmmm, have you seen steel against steel? think they're "touching"... ummmm, rubber...

qqqqqqqqqqqqqqqq My response: Oh yes, I was typing while you posted this, so it'll seem that my post "ignored" yours, not so, I just NOW found yours after writing mine one minute ago. Yes, that Dr Ians thing was helpful and I DID read it, yes. And yes, I acknowledged that f CAN be more than...

Well, you guys have helped a lot, and tho we don't agree on EVERYTHING, you provide VERY GOOD thought provoking stuff, and it gives me incentive to look even further, so you've got answers AND you're a catalyst. Thx. I'd love to see documentation on those tires with f=5 [I believe you, just...

qqqqqqq Yes, but only with SOMETHING adding the downward Force, right? like wind downward force on the slanted surface? qqqqqqq LarryR thanks ya'll... does anybody else know about these tires that have f=5?

Thanks for doing that so quickly; so I made this chart and if I DID make errors, pls let me know. So yes, the first two DO keep their accel rate up, in fact it INCREASES during the trip, but the second two are more like I'd expect; decreasing accel with progression down the track. Published...

I did a calc on all the 9 pcs of data that I COULD read, and he accel DOES IN FACT DECREASE as the velocity increases [kinduv normal in my opiniion] ... NOT approx constant as you had suspected. Good graph tho. LarryR : )
