Inertia, rigid body motion and angular momentum problem

[raphre]

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...

hi raphre! welcome to pf!

(try using the X² icon just above the Reply box )

general plan for these problems …

i] decide where the unknown force is
ii] start with an equation in which that force doesn't appear

in this case, start with a https://www.physicsforums.com/library.php?do=view_item&itemid=175"
