Web11 Apr 2011 · The extensibility and tensile strength of spider silk in general, combined with its light weight, enable it to resist damage from wind and from being pulled by anchoring points of the web. Additional Questions: 1. How do strength (as in tensile strength) and stiffness (as in Young's modulus of elasticity) differ conceptually?
WebSpider silk, also known as gossamer, is a fiber spun by spiders. Spider silk is a remarkably strong material. Its tensile strength is comparable to that of high-grade steel — according to Nature [1], spider dragline silk has a tensile strength of roughly 1.3 GPa, while one source [2] lists a tensile strength for one form of steel at 1.65 GPa. WebIn order to calculate the tension in Spider-Man's web, we must use centripetal force, the net force acting on Spider-Man. The centripetal force is the force directed toward the center …
