Re: Go stand in the corner, Chris
Sorry guys, I've been sleeping and trying to dodge a hurricane so I failed to note that this (enjoyable) diatribe had switched to a new thread (if some of you don't like it then why don't you just not watch it - there seems to be planty space on the board for it and the owners have not voiced any co...

Re: Green Laser pen
Please don't read this Chris - I'm no physicist but would like to add my little for the benefit of others who might want to read it. I BELIEVE there is no increase in mass when a body is travelling - where does anyone think it would come from - To incease mass we would have to add atoms or atomic pa...

Re: Green Laser pen
This is fun ! hands up ! guys - Vote, as Chris previously suggested in one of his posts Who really believes that he even has a clue as to what he is talking about. There is absolutely no doubt that Chris has a great, worthwhile knowledge and experience of electronics which is,relatively, a gift to a...

Re: Green Laser pen
As I suspected - your reply is an absolute bunch of BS -- Mass increases with velocity squared - only in Einsteinian Physics - in preactical cases the mass stays the same and the kE increases as velocity squared. The stuff about foot/pound = non-standard and pound.foot being standard is also 1st cla...

Re: Green Laser pen
OK Chris - The insults are tiresome and juvenile. - In your last post you were burbling on about acceleration, work expended to accomplish etc. It seems fairly clear to me that you are familiar with these words yet can't relate them in math. form. If that were not the case then you would have expres...

Re: where does the power go?
Chris (LOL), As part of your continuing English and engineering Units lessons - (i) You use a capital 'S' with Scottish (ii) if you choose to condense 'I am ' into 'I'm' then you have to use the apostrophe as shown.

...passed his tests . . . What language can the tests have been in if they didn't require some proficiency in use of the English language ?. . . furlongs do make up rods and chains . . . Nonsense 4 rods (5.5 yards) = one chain (22yards) = one furlong (220 yards) Do not rods and chains make up furlon...

Typos again ! For " in the errors of their ways " read ' see the errors of their ways " Forgotten point - furlong.stones per fortnight is OK with me - One furlong.stone per fortnight is, in fact, exactly equivalent to 1/720,000 horsepower i.e. one one seven hundred and twenty thousand...

Torque is the factor from which all HP is derived- wihtout torque there is no HP equation to derive any work from !- The product of a force and distance is torque ! 746 Watts of potential is the "same as " or "equal to " 550 pounds feet of potential (Stored) energy) ! - What abso...

Re: where does the power go?
I guess we will just have to leave Chris with his 'pounds.ft' while we, and the rest of the world use 'ft.lbf' Something tells me that I went to school before Chris did and I was very clearly taught 'foot-pounds' then. I did find a reference on Yahoo which said that James Watt used the term 'pounds-...

Then Aussies always were a hot-assed bunch - Does anyone think that this makes a case for making all carpets intrinsically safe ? (Or just explosion proof ?)

Re: where does the power go?
I like the ' doing calculations in the head part ' - According to my 'head' calculations - (which have equal probabilities of being right or being wrong) if the VW fan were of such a diameter (12 - 18 inches .?) that its' area were 1.0 sq ft. then, to absorb 4.5 hp the air would have to be accelerat...

Re: Generate 7w of electricity by walking
Definitions seem to be dependent on the source? My definitons are Watts are units of Power. Power is the rate (In work/energy units per unit of time) of doing/consuming/generating work or energy. Energy units are Joules, Btu, ergs, Newton.Metres, ft.lbf etc. The term Watts per Second (W/s) has no pr...
