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.
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.
What is the most common method of preventing the accumulation of static electricity?
The most common method of preventing the accumulation of static electricity is grounding. Grounding provides a path for the static charge to dissipate harmlessly into the ground, reducing the risk of static discharge. This is often achieved by using conductive materials or grounding straps.
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 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...
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 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
Who do some car owners fix to their cars a piece of fine chain which drags on the road?
static discharge
How is ben and jerrys ice cream transported to the stores?
Trucks will deliver it to the warehouses of the grocery chain. From there, loads will be assembled onto trucks which will service the stores. If any of the stores are to be restocked with Ben and Jerry's ice cream, it'll be loaded onto those trucks.
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
Do 2011 Toyota corolla have timing 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
