It is a drop-test where a sequence of vertically stacked masses impact one another in a controlled manner. The sequence happens as such: Upon being dropped the lowest mass impacts a spring at the base. It rebounds off the spring and impacts the next mass in the chain (which is lighter). This...
Hi thanks for this!
@IRstuff The impact time is from the initial contact between the lighter mass and the spring attached to the heavier mass, until the masses are no longer in contact, i.e. the spring is compressed until the relative velocity between the masses is zero; the potential energy in...
Hi,
I have what seems like a relatively simple problem: I have 2 cylindrical copper masses that oscillate on the same vertical shaft, with the lower mass being 80g and the higher mass being 30g. There is a compression spring (stiffness = 5 N/mm) attached to the top of the heavier (lower) mass...
