The problem involves calculating the weight developed by an object swinging on a pendulum-like arm, specifically a 20 lbs weight on a 30 inch arm, as it drops from a 2 o'clock to a 5 o'clock position. The context includes considerations of circular motion and the forces acting on the object during its swing.
Some participants have provided insights into the importance of using SI units and the relationship between angular velocity and force. There is an ongoing exploration of how to convert angular velocity into a weight measurement, but no consensus has been reached on the specific calculations or methods to be used.
Participants note the potential confusion regarding the use of RPM and the need for clarity on the time measurement for rotations. The original poster expresses uncertainty about where to start with the calculations.
did you mean that at that juncture, on this sort of pendulum, the thread/rope(whatever) is suddenly cut, and the object is dropped on a weight measure?...if this was dropped on a scale measuring lbs.
