I think you are referring to 'rumble strips.' If your automobile strays onto the shoulder of the highway, both the sound and the vibration your tires make as they drive over the rumble strips will alert you so you don't run your car off the road.

What are the types of chasis in bikes?

Bicycles aren't considered to have chassis, they have frames. The traditional bike is sometimes referred to as a "diamond" frame, as it's made up of triangular shapes. After that it's more about bike types than frame types, but I guess you could divide them into rigids, full suspension, recumbents, unicycles, trikes and tandems.

What are the types of gearboxs used on hgvs?

Specifics for European trucks, I'm not sure about, but universally, the manual shift transmissions will be unsynchronised, consisting of anywhere from 8 to 18 gears total, although synchronised gearboxes with just five, six, or seven gears are often seen on single axle straight trucks/rigids. There are also automatic transmissions available, as well.

What is a hardtail bike?

A hardtail is basically a bike that hasn't got a rear suspension. It's usually used for Mountainbikes. MTBs are available in three "flavors":Rigids (stiff fork and stiff frames)hardtails, HT (suspension forks and stiff frames)Full-Suspension, FS (suspension forks and suspension frames)Other bikes as a rule don't have suspension components, so it's pretty much only for MTBs that you need to keep track of the different styles.

How many life rafts where on the titanic?

There were 16 rigid wooden lifeboats, each one of which was capable of holding 60 people, plus four collapsible Englehardt boats, which had rigid keels and waterproof canvas sides that could be raised and propped up with wooden stakes.None of the latter were salvaged, and presumably eventually sank or ended up just drifting about the ocean until they either rotted to pieces or washed up on some remote shore. All but three of the rigids were salvaged by the rescue ship RMS Carpathia, the three that weren't were set adrift- however, one of these was upturned and another one half-sunken anyway, so they themselves probably ended up going down in rough weather.


How many lifeboats on titanic and how many used?

The Titanic carried 20 lifeboats enough for 1178people.They were legally required to carry enough lifeboats to carry 1060 people.The boat was designed to be able to carry 32 lifeboats, but did not as it would have made the top deck too cluttered.So all in all the Titanic carried the correct amount of lifeboats.To save every person on the ship there would have had to be, 40 lifeboats.


Did the people on the titanic life boats macke it to land?

They spent most of the night on the open sea before being picked up by the Cunard liner RMS Carpathia, which was the nearest vessel to pick up and respond to her SOS message and dashed 58 miles though the night to the rescue.The Carpathia was a small single-funnel liner on the Southern Atlantic route, under the command of Captain A.H. Rostron- built in 1902, she was taking a group of mostly elderly American passengers on a cruise of the Mediterranean, and was nowehere near either the size or the standard of luxury of the Titanic.She arrived on the scene of the sinking at dawn, about 4.5 hours after the Titanic sank- up until then the sea had been calm and conditions clear, but at that point the ocean was starting to become choppy and visibility misty. The Carpathia used her own bulk to shield the lifeboats from themselves colliding with small icebergs- after all of the survivors were safely aboard, 13 of the lifeboats were salvaged and stowed on the front deck, which was most of the rigid boats- the remaining 3 rigids, plus all the collapsible ones, were set adrift.The ship then headed for New York and docked at Cundard's pier to disembark the 705 survivors, whilst the salvaged Titaniclifeboats were moored at the White Star Lines pier (they were later re-used on other White Star Lines vessels).The Carpathia was herself sunk by a German submarine on 15th July 1918 during WW1, whilst part of a coal convoy headed for Boston- nobody died in the sinking. Her wreck was discovered in 2000, lying at a depth of 500 ft about 120 miles West of Fastnet, Ireland.


What bikes can take a 260 lbs person?

At that weight, you're beginning to push things a bit. Plenty of bikes will hold up for casual riding, but going over a curb too fast or things like that can certainly break things. First off, I suggest you look for a rigid, steel frame mountainbike. You might be tempted to go for a suspension bike, but the good stuff, like air/oil suspension won't be rated for your weight. On top of that, rigids are cheaper anyhow. Make sure the frame is big enough for you. Lighter people can run long stems and long exposed seat posts. For you, that's not ideal. For comfort, fit the widest tires that frame/fork can take. Something like Schwalbe Big Apple comes to mind. Next thing is wheels. Look for 36 spoke(or more), and wide, beefy rims. For casual riding, pretty much any 36H front wheel will do. Rears are trickier. If you want external gears, see if your budget allows for a 40 or a 48 spoke tandem rear wheel. Or go for one with internal gears or a single speed. Wheels w/o external gears are inherently stronger, so a sensible choice if you want to stay within the easier available 36H. And do try to shop from a reputable, local dealer. Dedicated riding at your weight will require better-than-average stuff, which takes some skill to source and put together.
