What are the dimensions of the wheels? (required to convert rpm to a speed). What gradient is the wheelchair being pushed on? Uphill/downhill, what angle?

Your 1994 t-bird when started runs at 3rpm with check engine light on what can you do to stop it?
One suggestion would be to check the "throttle position sensor". Basicly this is nothing more that a variable resistor. I would recommend possibly purchasing a Chilton's Manual, available from most auto parts stores, excellent troubleshooting steps/ideas.
RPM stands for on a vinyl record?
"RPM" is the abbreviation for "rotations per minute." The RPM of a standard 12" vinyl record is approximately 33 1/3 rotations per minute. When vinyl records are made, the grooves are "cut,"or created, at a certain speed. In order to ensure proper and accurate playback of the sound information created in the grooves, the record must be played at the same speed that it was cut at. The RPM of most 7" vinyl singles is 45RPM; sometimes, if a musician wants to be able to fit a longer song on a 7" record, it will be cut (created, remember?) at 33RPM, thus resulting in a longer playing time. This is because it takes longer for the needle to reach the end of the record at this slower speed. As previously stated, the standard RPM for 12" vinyl records is 33 1/3RPM, but occasionally artists will choose to have their 12" records cut at 45RPM. This is more common in 12" vinyl "singles" - 12" records with only 1 or 2 songs per side. However, it is not recommended to cut a 12" record at 45RPM - there are many reasons not to. Sound quality suffers for numerous reasons. (I have one - it sounds terrible) The olllld shellac records made in the early 1900's were cut at 78RPM. Most modern turntables ) don't have the capability to play these records; they also require a different needle than vinyl records. Playing a 33 1/3RPM record at 45RPM will result in a higher pitched sound and a faster playing speed than intended. Playing a 45RPM record at 33 1/3RPM will result in a lower pitched sound and a slower playing speed than intended. Hope that helps. ~bryan
How much can a vinyl record hold?
http://www.urpressing.com/advice.htmlPreparing Your Master for Vinyl Production Let's start with the basic truth: The volume of your record is directly linked to the total time of each side. This means if you intend to have it played in clubs by DJs, the most time per side should be around 12-13 minutes for 12" records. When the side length is less than 9 minutes, the loudness will be at the maximum for 33 1/3 rpm cuts. However for EVERY MINUTE over 13 minutes per side, you lose about 1 db in volume on the side in most cases. Now let's talk about so-called "S" distortion (sibilance). When the master has too much high frequency on vocal "S", "T", and "F" sounds, it will end up OVERLOADING the playback styli, causing noticeable distortion. This also happens when hi-hats, cymbals, and any high frequency sounds that are in your mixes are too hot. This can also mean the louder your record is cut, the worse the problem will be. So have all the fun you want for compact disc mixing. But for vinyl mixes, I suggest BEFORE you add compression or any digital processing, leave the mix for vinyl production as untouched as possible. Edit: The above answerer has totally ignored what I suspect your question was about - the longest 331/3rpm 12-inch LP vinyl record. I don't know for sure but towards the end of the LP era there were instances of in excess of 35 minutes on each side. The level and quality of the transfer suffered slightly, particularly towards the centre (end) of each side.
Is Honda d15z8 3 stage?
no, d15z8 is vtec-e, which means below 2.5rpm and 3rpm in 5th gear engines goes in 12valves mode, then after these rpm or full throttle below these rpm it goes to normal 16 valves mode and works like non vtec engine and nothing similar like "vtec just kicked in". so basicaly it has no third stage (wild mode) that has d15b. sorry i just need to correct this answer above... d15z8 engine does have the wild mode.... it kicks in around 5400 rpm, it also has economy mode below 2500-3000rpm but its not 3stage vtec, the economy light comes on at low revs that's all... the valve timing changes at 5400rpm. since 16v is more efficient at high revs and 12v is better at lower revs, vtec kicks in just when a 12v engine would peak and a 16v engine would begin to get lively, giving u the best of both worlds
What are the advantages and disadvantages of the gramophone?
Advantages: You can just wind it up when there is no power because the gramophone doesn't run on batteries or power plug. Easily portable The gramophone was very popular in the UK from 1900 right through to the 1950s. In 1948 the vinyl LP record was introduced with a much longer playing time. These new LP records rotated at a lower speed 331/3RPM and had much lower surface noise and were more durable. the advantages of records made from non‐breakable material, with greatly improved recording techniques, and with light‐weight pick ups and sapphire and diamond needles Disadvantages: Its very big The volume is always at 1 volume you can't change the volume (Louder - Quieter) You had to give it a lot of attention you had to wind the gramophone up it didn't just play continuously . The first gramophones could only be operated via a hand crank. This wasn't exactly a treat for the ears, as was reflected in the low sales figures. It wasn't until the introduction of the spring motor and Caruso voice that the gramophone made its breakthrough. Only the rich could afford it Limited choice of records
What was used to listen to music during the 1970's?
Music was heard during the 70s using several mediums. The first that comes to mind is the two or three speed phonogragh or HiFi. The speeds were 45rpm, 33 1/3rpm and the third speed was 78rpm which was on its way out. The first two were the most popular. A send method of listening was an AM/FM radio, either mono or stereo. The third method was a reel to reel (7" reels were very popular) tape player. If you wanted to listen to the music in your car, again, the AM/FM radio and 4 track tape players which were replaced with the 8 track player. The four and eight track players were stereo. All of the tape players, except for the cassette, used 1/4" wide tape. The cassette tape was 1/8" wide. The recording/playback speeds of the reel to reel were 15, 7.5, 3.75 and 1.875 inches per second. The faster the speed, the better the quality of the recording.
