Hello all,
I'm pre-college, really looking forward to joining you all someday, and I'm hoping someone can help with a problem I'm working on for an AP class at my school.
I'm trying to make a lever that, when pushed down on one end, will transfer the energy on the other end straight up a wall, instead of a curve. I've got a little idea worked up, that I've attached below: A is one end of the lever, B is the other end, C is my solution to transfer the energy straight up - a rotating column that always points up, transferring the energy in the direction I want. The end goal is that the lever is to deliver a load (that will be placed on top of pt C), to the top of a wall but I can't figure what kind of joint B and C should have that would keep pt C always pointing straight up/always delivering the energy straight up. Anyone have any ideas?
Many thanks for any help!
you're working the angles there
Make B a swindel
The idea with a plank looking up on the edge of a lever is jack as you're either way mostly elevating point of contract (uncless point C can maintain upright posture while being almost above the bottom bar). Going along the same lines you could base of the plank not rotate around axis
there's most likely a better way of doing it, but im contend with besting you while dropping out of high school

What you are trying to design is called a 4-bar mechanism (use Google to see examples). Just because point C needs to travel linearly (vertical in your case), does not mean bar BC needs to remain vertical.
Many thanks for pointing me in the right direction
