I’m sure you remember this scene in Spiderman 2:
How realistic is this scenario — is it actually possible for a web of spider silk to halt a speeding metro train? Apparently, the paperit is.
Assuming that the ‘web’ has eight strands of silk, each with a diameter of about 5mm, the stress it has to withstand is about 1.3 GPa. Apparently, some spider silks do have such high strengths.
Hat tip: Discovery News.
Now, I guess someone will step forward to ‘prove’ that it is actually possible for Spiderman’s arms to hold things up right until the end!
