Questions & Answers
Question : Building a sumo robot. A physics question about motors, torque, and gears...?
The objective of the contest is raw pushing power. I have (3) duplicate electric motors at my disposal.Would I get more power from attaching all three on a single axle that is torqued up with a gear ratio? Or would it be better to have each run independently, with its own gear set?We are using the lego mindstorms robotics kit, and are limited to those parts, for anyone familiar. Any other suggestions that may pertain to robot design or further increasing the pushing power are welcome.
Answer:
I would attach all three motors to a single rotor, with one big gear to torque up the axle. If the single large gear is large enough, you can drive it with all three motors, one at, say 2:00, one at 6:00, and one at 10:00.The only tricky bit is calibrating the three of them so that all three of them drive the large gear to the same position at the same time. Otherwise one might push ahead of the other two, and you'd only get torque from that one.If you CAN, you might want to consider using small belts instead of gears. Belts would be easier to calibrate, though if you're locked into legos, I don't know if they have those. The belts might not provide as much power before they slip, but they'd certainly be easier to calibrate.

Question : Skyrim: How not to die?
What is the best combat build? archery seems to suck. (im a woodelf archer) and i find it hard to take out more than 2 bandits at a time when im spotted using a bow ive found one handed and shield works best so far. any builds, set ups, tips, perk placements, gear. any combat advice would be appreciated
Answer:
What I would recommend is to pause the game and then go to "gameplay settings" and then set the difficulty lower so the game becomes easier. Then once you level up and become a better fighter you can turn the difficulty back up. * Changing the difficult does not affect the game in any way except making it easier, like it won't affect the storyline.

Question : Bicycles gear ratios...?
if u went to a shop that specializes in bikes and told him that you wanted a set of gears and that you had a list of gears would he be able to build a custom set using the gear ratios you gave him....?Additional Detailsand if he could would he be able to use the following...2.5:12.07:11.69:11.38:11.18:11.04:1the top 6 gears would be for the back whereas the final would be 5:1...if it would be too short what final gear ratio could i use...?
Answer:
I'm not sure how you are defining your ratios. The normal way is to describe gears in "gear inches", where:GI = (number of teeth on the chainwheel) x (wheel diameter in inches) / (number of teeth on the rear cog)So for a 9-speed road bike (nominal 27" wheels) freewheel / cassette with 11, 13, 15, 17, 19, 21, 23, 25, 29 teeth and a 49 tooth chainring the gears would be: 120, 102, 88, 78, 70, 63, 58, 53, and 46.While you can use the ratios direct the advantage of gear inches is that it allows gears to be compared between different types of bicycles (e,g, road, mountain, hybrid, BMX).Now to the heart of your question. If your bike takes a cassette you will be limited to the gear ratios defined by the several cassettes that fit your hub. On the other hand if you use a freewheel (see link for difference) it can be disassembled and different sized cogs used to allow more customization. There are some limitations on the smallest and largest (and the teeth differential between adjacent cogs) to ensure good shifting, but by playing around you can get pretty much what you want.Talk to your local bike shop if you aren't sure. Otherwise you can order parts on line -- once you define what you need.

Question : Can you buy Halo Mega Bloks in just the building blocks not the sets?
Ive been looking but unable to find Halo mega bloks building blocks. As in just the pieces themselves not geared toward building a particular vehicle or building but so i can craft my own buildings. Are they out there or do i have to buy a bunch of the vehicle ones and use the pieces from them? Thanks for any help.
Answer:
Sorry to get the Halo themes bloks you'll have to cannibalise a pre-made set.

Question : DIY project assistance?
Hello all,I am looking for somewhere I'm able to buy small hobby sized gears for a project I'm building. I need to reduce the speed of a powerful 12V DC motor similar to the one you'd find in a small cheap air compressor to drive a piston I'm building to pump water slowly. I'm looking at reducing the speed to as low as 30RPM which should allow plenty of force from the high speed motor to drive a piston head up and down a PVC pipe. I'm not sure of the motor I'm after yet but I know the motor will output 15,000 to 20,000 RPM and will have to travel through several gear-sets to reduce to the 30RPM as not to over-do my DIY piston (its more for show anyway so low speed is good).So what i'm asking you guys is:1.) Where can I buy gears needed in Australia (preferably near Adelaide so I won't need to post them and they are only needed small. Also I probably won't want plastic due to the force and high speed)2.) What type of gears should I use (Worm or normal etc.)3.) What ratio will I need through each set to achieve such a low speed? For example 50:1 (input 50 rotations to output just 1)Thank you for your answer A.V.R., you make a good point of a bicycle wheel being used however, it is very large. If there is another option I could use which is much smaller it could be more helpful. I will keep the bicycle wheel in mind as it is a very good idea and cost-effective.

Question : I have a 1998 Suzuki Esteem. When the motor is cold,the transaxle has difficulty shifting to higher gear.Why?
Here are the details: I have a 1998 Suzuki Esteem with an automatic transmission. Good car, but it has a problem that I was unaware of until our company moved to a new building and winter set in: when the motor on the car is cold, the automatic transmission does not shift into highway (high gear or overdrive). When the car is warmed somewhat (not even operating temperature) the automatic transmission will shift into higher gears with ease. What I want to know is why does this happen and should I be concerned?I am writing this on March 4, 2006. I just changed the transmission fluid (I'm a real stickler about maintenence) two months ago and it seems to be running at a proper level--although I will check it again, to make sure. So far from the answers to the questions it sounds like that as long as I warm up the car before pushing the car to highway speed I should be o.k. But the question is still up, so any other information is welcome. Thanks to all who have answered...
Answer:
You should not be concern about this at all. Suzuki is a foreign made car and unfortunately was't design for cold climates. However, on very cold mornings or if the car has been sitting for a while just allow it to warm up a few minutes and everything will be fine.

Question : What is a good and inexpensive crank set?
I am building a fixed gear bike and I am somewhat under a budget. I have been looking at these 50 dollar crank sets but as soon as I look at the reviews, everyone says they are of very poor quality. I am looking for a crank set, under 100 dollars that is decent, not the best, but decent. Anyone have any recommendations?
Answer:
Find an older, upscale-ish japanese invasion bike with Sugino VP cranks. You should be able to get them for less than $10. Buy a set of five half size crank bolts. Remove the big ring and put the small ring in its place on the other side of the crank spider. Attach with the new half size bolts. Voila.For about $15 you have a killer, super-strong fairly lightweight crank. The VPs are dead ringers for the Sugino track crank which goes for over $100. You can get Sugino stuff anywhere if anything breaks or you want something other than a 42 tooth ring.

Question : Building a new PC. ASRock N68C-S UCC Motherboard & AMD Athlon II 465. Need Some Advice!!?
Hi there,I am scrapping my old AMD Athlon 64 x2 system and now building a new one. I used to build alot of PC's when I was younger but now I am scratching my head with how far pc technology has come on!!Basically I am wanting a pc to use on my home tv for gaming, internet access and movies.I don't have alot of money to spend but I will pay for high price gear if its worth my while.What I have purchased so far:ASRock N68C-S UCC MotherboardAMD Athlon II 465 3.1GHz Quad Core ProcessorThermaltake Wing-RS ATX Case with 500w PSUSeagate 320GB Sata HDD (to use as primary drive)Maxtor 1TB Sata HDD (for storing films and music)Logitech diNovo Edge Wireless MediaBoard (brilliant keyboard for home tv setup)The 2 vital parts I need to get the system up and running is Ram and a high end value graphics card.Now as far as I understand the motherboard I have has 2x slots for DDR3 ram, and 2x for DDR2. I'm running a AM3 processor so running DDR3 is a possibility. I also think the motherboard will support 8gb of ram on either sets of slots, but I'm not certain.With the ram, what I want to know is how much is in difference between DDR2 and DDR3? Is purchasing 4GB of DDR2 good enough or is DDR3 more appropriate? or should I even run all 4 slots with a total of 8GB?The graphics, to be honest I have my eye set on the Radeon HD4650 1GB. Very cheap but iv heard good feedback, some people claiming it knocks out most of the Nvidia Geforce range. I just want a second opinion on that before I buy it. £48 brand new Sapphire's version, it seems too good to be true for that price!Thanks, Dan
Answer:
4 GB is all you need. As far as video cards go, the 5670 Radeon is better than the 4650 for only $70-75. The 5770 Radeon is probably your best choice at around $100-110. Your 500 watt power supply won't be good for cards much better than thatI wouldn't suggest an older card like the 4650

Question : Using gears to get more power out of my electric motor?
Im trying to build a machine that uses an electric motor with gears that are attached to a pole that will lift a 5-7 lbs small monitor. So far I have been un able to lift it because my set-up is not strong enough. I use a worm gear connected to 1 gear thats about 2 inches wide, that is connected to a long strip of teeth on the pole. What kind of motor might I need for this and how should i set up my gears that will give me enough power to raise the weight? Thanks!!!!
Answer:
Gears don't change the amount of power, they change the force or torque, increasing it at the expense of a slower motion or RPM.You need to decide how fast and how far you want to raise the weight. Then calculate the power needed (weight x distance is work, which is energy. divide by time to get power). Add a factor for motor losses and a factor for gear losses to get HP needed.Then from the speed the weight is moving, calculate back through the gear chains to the motor RPM. or start with the RPM and find the gear ratio you need to move the weight at the speed you want. Check the losses in each gear, and use that to check the numbers.
