I was googling this very thing looking for the answer. I think it's because a longer rope reduces the vertical angle, so you're doing more pulling and less lift/pulling.

Why is it easier to pull down on a rope over a pulley than to pull down on a rope thrown over a wood beam?
A pulley is a wheel and axel which reduces the friction created by a cable being pulled across it, a rope over a wood beam would have increased friction, making it more difficult to pull. Numerous pulleys would reduce the amount of tension force required to move a load, making it easier to pull.
Why is it easier to pull than to push?
Whether it's easier to pull than to push depends on the circumstances, there is no universal principle here. If you're using the pulley suspended above you can add your weight to your arms force and thus amplify your effort(pushing a rope doesn't produce any result of course). If you were to move a heavy stone block it might be easier to push it, if there's no grip possible to pull.
What do pulleys do to the direction of a force?
If you have a pulley, it will make lifting an object up easier. since it is easier for someone to pull something down then pick up, a pulley is made to pull the object up, in a way where you only have to pull down. (Because that's easier) for example, if your friend tries to life you off the ground, that is a lot harder. but, if you put a rope over a branch, hold on to one end, and have your friend pull the rope down or away from you, which will raise you up, it is a lot easier, and more convenient
Does the pulley size make a difference?
no. the size of a pully makes little difference to its action on a rope as the only thing changing is how much of the rope is in contact with the pully and since the pully rotates it makes it no easier or harder to pull the rope.
How do you stop the loading hanging on red dead redemption?
You shoot the rope, this is easier using dead eye.
Is it easier to pull when the load is closer or further away?
If you are simply pulling an object with a rope, say, such that the rope is parallel to the surface over which you are pulling then, ideally, the distance between you and the object should make no difference.
How would you measure the force needed to lift 50kg of shingles onto a roof using a pulley?
50 kg (on Earth) weighs about 110 pounds. If you're using a simple, singlepulley with a rope passing over it, then that's the pull you need on the rope tolift the bundle of shingles. If you're using a block and tackle arrangement ofmultiple pulleys, then you'll get away with much less pulling force on the rope,but you'll have to pull the rope much farther.
How do rope and pulley change the force of an item?
A rope and pulley lessen the force needed to pull an item, but it increases the distance that you have to pull it. It also changes the direction that it moves: you pull the rope down, the item goes up.
Which type of Personal Floating Device would you throw to someone who has fallen in the water?
A foam ring with a rope attached can be thrown toward the person--you would keep hold of the end of the rope. Once they grab the ring, you can pull them in using the rope.
Why a person walking on a rope carries a long stick in his hands?
The long stick lower center of gravity and makes it easier to keep the balance.
How do you make a new elf come to you?
Keep it tied to a rope and pull on the rope
What can pulleys do?
pulleys can pull things up by using 1 rope or more(depending on how many wheels), and 2 or more wheels
