1. The problem statement, all variables and given/known data A uniform thin rod of weight W = 100 N is supported horizontally by two vertical props at its ends. At time t = 0 one of the these supports is kicked out. Find the force on the other support immediately thereafter. 2. Relevant equations Sum of forces?? 3. The attempt at a solution I really don't understand how to even approach this problem. My guess is that its 50 N because each support holds half of the rod. Any help would be greatly appreciated !!
