circular to oscillatory motion
[COLOR=#000000][FONT=verdana]Hi all[/FONT][/COLOR]
[COLOR=#000000][FONT=verdana]I'm from Bioengineering and unfortunately not too expert on the mechanical side. I'm making a device for which I need a mechanism to transform circular motion into oscillatory motion. I found the mechanism in the picture below:[/FONT][/COLOR]

[COLOR=#000000][FONT=verdana]In my device, the oscillating 'stick' would cover an angle of 170 degrees.[/FONT][/COLOR]
[COLOR=#000000][FONT=verdana]My questions are:[/FONT][/COLOR]
[COLOR=#000000][FONT=verdana]Is the oscillatory motion actually sinusoidal? (ie is the velocity/position actually sinusoidal, or are they just approximated to sinusoids due to the small angle shown in the picture?)[/FONT][/COLOR]
[COLOR=#000000][FONT=verdana]If it is/can be sinusoidal, is there a straight forward way to go about to find the specs (size and position of rotating wheel...) of the system? [/FONT][/COLOR]
[COLOR=#000000][FONT=verdana]Suggestions on different mechanisms I could use are very welcome. (I thought of using a cam but the oscillating 'stick' would in my case probably be jumpy due to the high velocity and low weight needed).[/FONT][/COLOR]
[COLOR=#000000][FONT=verdana]Thanks everyone!![/FONT][/COLOR]
