I "fire" traditional recurve bows and honestly it ends up being a lot of core, back, and your front side shoulder, but this image is funnier.
I guess also another thing that gets me is when they are fire from the hip, with no anchor point. You draw back the bow to the same spot every time, then move your bow hand to aim. Radically changing how you draw, while hitting precision shots at varying range is like John Whicking archery, but nearly everyone with a bow in movies can do it. And they almost never wear gloves on a bow that has to be hundreds of pounds of draw to go through armor. How are your fingers not worn to bone?
Also arrows are pretty custom depending on draw weight, tip weight, draw length, and there are various types. Where do these perfect arrows you need all come from, hrmmm Legolas?
I am now realizing I took this meme way too seriously, but I've already typed it up, so here we are.
I never blamed the archer on the walls of Helms Deep. Waiting for the enemy to get all the way up to your walls was dumb enough, but waiting while having drawn your bow for what must've felt like ages for a human archer, is fucking rediculous. Terrible leadership.
You don't want your archers to be excausted before the battle even starts, just so you can look really unbothered on top of your wall.
I agree, but it’s obviously done for the tension in the movie. It wouldn’t be as exciting, if the archers were just chillin’ while the Uruk-hai were charging. 😄
Versimilitude is important. Self consistency. Just because you introduce one unrealistic element doesn't mean everything else that is unrelated to it should be thrown out the window, too. The existence of a magical evil spirit entity doesn't change how nonmagical humans would interact with everyday physics.
Fiction only really works when it takes itself seriously. If they just don't follow any rules or logic then you know there's no reason to care about what's happening, because the author didn't. In LotR the archery follows the logic from out world. Yes, there's also magic and stuff, which all follows consistent rules in the universe. The magic does not effect the rules of archery. Maybe elves can be more agile with their bows, but it should still be grounded in the rules of their universe.
Short answer: no, they don't.
Modern compound bows use that cam to lessen the power needed to hold.
Older bows are like holding a spring extended, the further back, the greater the force needed.
By modern I take it you mean compound bows. No other types of bow have that. The force you need to pull back is at its maximum when at full draw. The exact scale of 0-100% through the draw varies with different bow designs, material and even age as it can permanently deform with repeated use.
