Conversion between two Harmonic Angular Motion

[QUOTE="DFornazari, post: 5467771, member: 593400"] [h2]Homework Statement [/h2] I need to find a way to do a conversion between the angular motion of a motor to the angular motion of an oscilating bar that is connected to it through a sliding and rotating collar. This way, every time the motor completes a revolution, the bar swings back and forth with a amplitude of 30 degrees in 0,2s (2x30º = 60º). The problem is that I can't find an equation to compare both motions. The motor angular velocity is 10π rad*s[SUP]-1[/SUP] [h2]Homework Equations[/h2] SHM equations (maybe?) [h2]The Attempt at a Solution[/h2] I've tried using Angular Simple Harmonic Motion, but I think that as I'm working with big angles, the error will be way too big. I also tried comparing the angles of both motions in a table (Motor Angle [0º,360º] x Bar Angle[-30º,30º]), and found an equation: θ(φ) = sin(φ)*π*sqrt(3)/9. The problem is that this equation works when you use φ = 0, 120, 180 and 240, but it does not appear to work when angles between those are used. I think that happens because the relation is not linear due to acceleration.[ATTACH=full]187592[/ATTACH] [/QUOTE]
