1. The problem statement, all variables and given/known data Two equal masses (m) are connected by a light rod of length L that is pivoted about its center. A downward Force F is applied to the rod at a distance L/4 from the pivot. If you ignore gravity, the linear acceleration of the mass is... O--------o--------O 2. Relevant equations torque= Ia 3. The attempt at a solution I don't know where to go with this one because gravity is ignored.
