Good morning to all, I am having trouble analyzing and assembling a mechanism that I thought simple.
I have a lever whose rotation tends to compress a spring, which acting on a barbell increases the contact force between the barbell and the cylinder (which is solid with the lever), i.e. increases friction between the barbell and the cylinder.
My problem is that the contact between the cylinder and the balancer is not a point (in 3d would be a line) but a curve (in 3d are two cylindrical surfaces with the same radius) and so I can't put a cam-follower connection.
I'm interested in getting how friction varies according to the rotation of the lever. I thought I solved by inserting an additional pin between the cylinder and the barbell, but when I analyze the mechanism with mechanism I have results that make me twist my nose.
How would you do that?
Thank you very much
