Why do gasoline trucks often have a piece of chain that drags on the ground?
To ground the vehicle against static electricity buildup. Gasoline is highly volatile.Added: Static electricty is discharged from the vehicle, via the chain, to the ground. Without the grounding chain an electric charge could build up a sufficient enough charge to cause a spark which could explode the vapors of the volatile cargo, or even an otherwise "empty" tank.
What is the most common method of preventing the accumulation of static electricity?
Ground yourself.The best way for cars and trucks is to weld a chain to the frame and let it drag on the ground.
Why do petrol tankers have a length of metal chain?
The chain is there to prevent static electricity building-up and causing a spark that could cause an explosion. Any static electricity is led down the chain to earth.
Your car door shocks you when you touch it?
It's called static electricity. The 12 volt system in cars and trucks are not enough to shock someone. Even 24 volt systems found in buses and heavy trucks are not enough to feel. So it has to be static electricity somehow.
Why some owners of car let a piece of chain hanged and dragged to the surface?
This is to prevent the buildup of static electricity. The chain dragging on the ground releases the static electricity. It's probably a bit of overkill to do this for a car, and the sparking produced as the chain drags over the roadway is likely worse than the static electricity would be. It can be important for heavy equipment like farm or construction machinery, though.
Why is metal chains usually attached to a petrol tanker?
Older Petrol-trucks were supplied with a chain or strap to discharge static electricity; this was because natural rubber-tires manufactured prior to the mid 1940's would generate a powerful static charge on the chassis of the vehicle which caused numerous fires during fuel transfer operations.Modern "Synthetic Rubber-Tire" actually have enough Carbon in the rubber compounds so they conduct enough electricity and any static electrical charge is dissipated back to the road surface directly through the tires. Now therefore there is no longer any need for a dissipation-strap or a Grounding-Chain".
Why do some fuel trucks touch the road?
Fuel trucks have chains which drag on the road in order to ground the vehicle and discharge static electricity back to the road. Otherwise, the fuel tanker might spontaneously combust.
Where to find mechanic tools?
Chain stores, automotive parts stores, Snap-On Tools trucks...
Who do some car owners fix to their cars a piece of fine chain which drags on the road?
static discharge
Why is sulphuric acid transported by tankers and not by train?
train contain to much static electricity due to its metallic body but trucks a truck discharges the static electricity to the earth, so if sulphuric acid is transported by train that would cause an explosion due the reaction of sulphuric acid and static electricity
Why is sulphuric acid transported in road tankers and not by trains?
train contain to much static electricity due to its metallic body but trucks a truck discharges the static electricity to the earth, so if sulphuric acid is transported by train that would cause an explosion due the reaction of sulphuric acid and static electricity
Does 2007 Toyota Corolla have a timin belt or chain?
A chain. The only engine Toyota makes anymore with a timing belt is the V8 engines in the Trucks, Tunda and Sequoia and 4Runner
