The original poster is attempting to model a plank of wood as a system of masses connected by springs and is seeking to determine the spring constant of wood. There is uncertainty regarding the specific type of wood being referenced, as wood can vary significantly in properties.
The discussion is ongoing, with participants exploring different types of wood and their properties. There is no explicit consensus yet, but questions about definitions and assumptions are being raised.
Participants note the variability in wood species and the implications this has for determining a spring constant. The original poster has not specified which type of wood they are modeling, leading to further inquiry.
