1. The problem statement, all variables and given/known data
Hi Everyone. I came across this problem:
A metre rule is clamped to a table so that part of its length projects at right angles from the edge of the table. A 100g mass is attached to the free end of the rule. When the free end of rule is depressed downwards then released, the mass oscillates. Describe how you would find out if the oscillations of the mass are free oscillations.
2. Relevant equations
Free oscillations occur when a body oscillates with constant amplitude and frictional forces are absent.
3. The attempt at a solution
I proposed establishing an equilibrium position. It seems imperative that I can record vertical displacements from an equilibrium position. But I am not sure how I can measure it. At some point, air resistance should reduce the displacements. If the maximum displacement after a few measurements are not constant, the metre rule is not subject to free oscillations.
