As a subject matter expert in the field of fictional materials and their properties, I can provide an analysis of Spider-Man's web strength based on the information available from comic books, movies, and other media.

Spider-Man's web is not a natural substance but rather a synthetic creation invented by the character himself, Peter Parker. The web fluid is stored in devices called "web-shooters" that he wears on his wrists. The strength of Spider-Man's web has varied over the years and across different interpretations, but it is generally depicted as being incredibly strong and durable.

In the comics, Spider-Man's web has been shown to support his own body weight during his acrobatic stunts and to be strong enough to tether himself to moving vehicles or even tow heavy objects like cars or buses. It has also been used to restrain powerful super-villains, indicating that the web is not only strong but also has a high resistance to tearing.

The web's strength can be attributed to the unique formula of the web fluid, which is a combination of synthetic proteins and other compounds designed to be both strong and flexible. The web is also designed to be adhesive, which adds to its utility in various situations.

It's important to note that the strength of Spider-Man's web is fictional and is subject to the creative interpretations of the writers and artists who work on the character. As such, the exact specifications of the web's strength can change depending on the narrative needs of a particular story.

The web line's tensile strength has been estimated to be 120 pounds per square millimeter of cross section. The 300 p.s.i. pressure in each cartridge is sufficient to force a stream of the complex web pattern an estimated 60 feet. (It goes significantly farther if Spider-Man shoots it in a ballistic parabolic arc.)read more >>
