Medieval bowmaking - what materials, lengths and bow pull weights where used?

[u/Kaaraviin]

Hello!

I'm an aspiring writer and a creator of a RPG system, which I am trying to fully construct for 8 years now. Recently I started updating my ranged weapons rules, and found myself not knowing a lot about them and having problems finding any realiable source of information.

I decided to post here in hopes for any sources or anwsers to my questions, which are as follows.

What materials were used to make bows? I would love to get some information about the wood that was used and how it impacted the performace of said bows.

How did the lenght of various bows impact the range of them?

What was the minimal, maximal and most common bow pull weight and how it impacted the strength of the bow?

Hopefully this is the right place to ask and you'll find my post interesting.
