The strongest synthetic fiber is carbon nanotubes.
The strongest organic fiber is spider silk. Both are stronger than silk, but I don't know if the nanotubes or spider silk is stronger.
Zylon®, the world's strongest fiber, contradicts almost everything we know about fibers and fabrics. Zylon is made by mixing a polymer called PBO (para-phenylene benzobisoxazole), while forcing it through a spinning machine.
Carbon nanotubes currently claim almost 22 million pounds per square inch on the high end. (150 GigaPascals) These are, by weight more costly than gold. They are difficult, and very expensive to make in any quantity.

Alot of times you will see articles comparing strengths to steel; The strongest steel used as a cord, or cable (tensile strength) is Maraging steel with about 250,000 psi Tensile strength. There are other steels with higher tensile strengths such as some Tool steels, (Carpenter Micromelt A11 ~750,000 psi, Tensile) however these are more prone to fracture when stressed in tension, so they are not used for cables. (Suspension bridges / suspension rooves.)
There are two Tensile strengths (tension / stretching) for all materials, Ultimate, and Yield.
For some brittle materials the two are equal, for all the rest the Ultimate is higher than the Yield.
All materials will stretch when pulled on. Elastic stretching is before the yield strength is hit.
Materials will deform permanently (plastically, as opposed to elastically) if they see stress above their yield strength.
Materials break when they see stress above their Ultimate strength (for tension they snap.)
Values below are Ultimate:
Kevlar / Twaron / Nomex (Aramids)
Density ~1.5 grams / cubic centimeter
500,000 - 600,000 psi Tensile strength.
Carbon fiber (non-nanotube)
Density ~1.8 grams / cubic centimeter
500,000-800,000 psi Tensile strength
Dyneema / Spectra (Ultra High Molecular Weight polyethylene, UHMWPE)
Density < 1 gram / cubic centimeter (floats on water)
500,000+ psi Tensile strength
Is lighter than carbon fiber / Kevlar
UHMWPE generally stretches many times it's length before it fails, think of plastic grocery bags, as the monomer (Ethylene) is the same.

Spider silk is the strongest natural fiber known to man. It is known for its incredible tensile strength and toughness, outperforming steel of the same diameter in terms of strength-to-weight ratio.
Magnus Samuelsson of Sweden won the World's Strongest Man competition in 1998. He is known for his impressive strength and accomplishments in the world of strongman competitions.
The Hercules beetle is considered one of the strongest living things in the world, capable of carrying up to 100 times its own body weight.
There is no definitive record of the world's strongest man in 1873. However, Louis Cyr, a Canadian strongman, was one of the most well-known strongmen of the late 19th century.
The title of "strongest man in the world" is typically given to the winner of the World's Strongest Man competition, an annual event that attracts participants from various countries. Therefore, the current strongest man in the world could be from any country that competes in the event.
No. Carbon nanotubes are the strongest man-made fiber, spider silk is the strongest animal-made fiber, and linen (from flax) is the strongest natural plant fiber.
The worlds strongest rock is diamond
Linen was known as the strongest natural for a long time.
The crocodile has the strongest bite in the globe.

It is not true because it isn't a fact. they have a competition every year qualifying the worlds strongest man. he may probably be the strongest wrestler in WWE but he is Certainly not the strongest man.
the worlds strongest shot gun is a mosberg
yes
muskegon, mi
israel is the most strongest country,then russia,then America
