Inertia, rigid body motion and angular momentum problem

Click For Summary
SUMMARY

The discussion focuses on a physics problem involving a uniform thin rod supported by two vertical props, where one support is removed at time t=0. The objective is to determine the force exerted on the remaining support immediately after the removal, expressed in terms of the rod's weight W. Key equations referenced include the moment of inertia I = M(L^2)/12, which is essential for analyzing the motion of the rod post-support removal. Participants emphasize the importance of identifying the unknown force and starting with equations that exclude it for effective problem-solving.

1. A uniform thin rod of weight W is supported horizontally by two vertical props
at its ends. At t=0 one of these supports is kicked out. Find the force on the other
support immediately thereafter - it should be in terms of W.



2. Homework Equations : I=M(L^2)/12



3. Don't even know how to start setting up the problem...
