Question

Hello I have a geometry problem, I'm trying to design a moving joint attached to fixed surfaces

Diagram of what i mean

The only length that is changing is that of c, I need a function describing it in terms of a and b or rather h.

Trying to design something in 3d modeling software and this is driving me crazy. I figure one of you might have an idea how to solve this. It is probably simple and I'm just out of it.

Note that a, and b are constants and so is m

Answer 1

a,b fixed right ?

Answer 2

yes

Answer 3

\(d1\neq d2\) right ?

Answer 4

or this line is middle ?

Answer 5

d1 and d2 are changing as well depending on the state

Answer 6

h = d1 + d2
at that state and they would be equal

Answer 7

d1 + d2 = a + b at hmax

h max being the maximum distance between top and bottom surfaces

Answer 8

you should just ignore m because they are probably not going to be useful in this problem

Answer 9

@Kainui

Answer 10

at state 3, h will be pretty close to zero, objects aren't going to enter into each other though

Answer 11

At state 3,

c = a = b sort of kind of steric hindrance will prevent this

Answer 12

this should be solvable I mean it is a pretty simple fold
