[MCU] If Spiderman was holding onto webs between 2 buildings, and yanked with all his Spidermany strength, would his arms or his webs snap first?

This is assuming the buildings ~~exist in a frictionless vacuum~~ are indestructible. I'm stumped because his webs have been shown to several tonnes (cars and the like) but then again his body is reinforced/strengthened from the spider juice.

The webs would snap first.  Firstly, they are made with common Earth components. Spider-man's physiology is unnatural, but his webs are self-made by Peter's own design.   And that said, they would be more prone to breaking simply by design.   He wouldnt design a web that could cause his own body fatal injury.
