    Undergrad How can I shake a thin box up and down sinusoidally without a cam?

    Yea its for a school physics competition - so I am keeping things as simple as possible - 1 to 10 Hz and about 5cm max of amplitude?

    Undergrad How can I shake a thin box up and down sinusoidally without a cam?

    Hi I have a thin box (e.g. like an A4 book) I would like to shake up and down sinusoidally. At the moment I have a flywheel connected to a beefy motor. I have tried using a cam to do it but it has proven not so ideal. What other methods can I use? Thanks
