1. if your going to use your trailer mostly for salt water, does it have to be galvanized...?

No, it does not have to galvanized. But, you will need to wash it off each time. If you do not it will rust. If you do use a painted trailer, pull the shackle bolts, and grease them with an anti-sieze grease or they will rust and you will never get them out. Check your axle for drain holes, if it has them, make sure you flush that area also, and check your frame. The advantage of galvanized trailers is that you do not have to do this to the level required of painted trailers. Wheels are the same thing, they have to be washed each time and touched up every scratch same as the trailer.

2. Where to buy good skateboard parts?

blackholeboards.com is extremely reliable. i've shopped there for skateboard parts numerous times and every time i get my stuff on time in perfect condition. if u dont live in pennsylvania, then u get no tax. if ur order is over 90 dollars, its free shipping. here is a list of good skateboard trucks, bearings, wheels: trucks: thunder, venture, and tensor. thunder has these trucks called thunder lights and hollow lights that are lighter and stronger than their regular trucks. i would suggest their lo trucks in 145 if ur skating a walmart board. (cuz usually they are smaller. bigger trucks for thunder come in 147 and 149 ideal for board sizes 7.75" and 8.0", respectively). ventures are really good, and tensors are good, but more expensive bearings: skate bearing size is standardized, so they should fit any skate wheel (including scooters and roller blades) bones reds is really cheap, and really durable. u will see these bearings mentioned all over youtube and the web, because they are just that good. easy to clean too wheels: autobahn is a good beginner wheel. their wheels are around 28 bucks, which is really good for their quality. spitfires and rictas wear down fast. my friend doesnt even skate that much, like maybe twice or three times a week, and he chipped his spitfires in like 2 months. suggested wheel size: 52mm

3. Why is it difficult to rotate the steering wheel of an ordinary car when it is at rest and relatively easier when it is at motion?

That's because rolling friction is less that static friction..!!When your car is at rest, Static friction resist the motion of wheels, But once it start moving it's the rolling friction that's happening in between the road and the tyres, It's lesser than static friction in magnitude, So wheels will turn easily..!

4. What size wheels spacers for my civic?

Racing, hills, and potholes have nothing to do with the wheels failing. It's the fact that you are putting space between the wheels and the hubs. Plus, you are changing the geometry of your axle/suspension/etc setup, so you will be damaging a lot more on your car than just that. Get wheels that fit your car, instead of trying to fit your car to your wheels.

5. How do airlines compute weight allowances for carry-on bags?

As all other answers have pointed out, the limit is most definitely on the total of the case and its contents.5-6 kg for a carry-on is just way too much. You should use another bag or case. Even with a hard shell, you can find cases that weigh under 2 kg for a carry-on, including wheels, handle and all, and some of them are very, very durable. I had a similar issue with full-size suitcases before. Before you even put anything in them they already weighed half of the allowance, so I was always struggling to stay under them. I switched to a lightweight hardshell (with 4 wheels) a few years back, and it changed my life, I nearly never have to fear being over the limit.
