Oscillation - car losing contact with bridge

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem related to oscillations, specifically focusing on a scenario where a car loses contact with a bridge. The context involves understanding the forces at play when the bridge is above equilibrium and how this affects the car's motion.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the dynamics of the situation, questioning how the car could lose contact with the bridge when the bridge is accelerating downwards. There is a focus on visualizing the motion and understanding the relationship between the bridge's acceleration and the car's behavior.

Discussion Status

The discussion is ongoing, with participants confirming each other's thoughts and attempting to clarify the mechanics involved. There is a shared understanding that the bridge accelerates downwards, but the implications of this on the car's motion are still being explored.

Contextual Notes

Participants are considering the scenario above equilibrium and the resulting accelerations, which may not be fully defined in the original problem statement.

The Attempt at a Solution



Ok so as the bridge is at a point ABOVE eqm acceleration is DOWN and at some point ACC down is greater than gravity acceleration.
This is all true but makes no sense to logically. How could the car lose contact with the bridge at this point. Is the car thrown into the air, or does the bridge simply accelerate DOWN faster than the car

yup! :biggrin:

ok, trying to visuallise this.
I presume this will though, above eqm, as the bridge moves DOWN towards eqm??
 
yes :smile:
