[SOLVED] Torque Homework Help 1. The problem statement, all variables and given/known data Here's the problem and I need to submit the answer online tonight!! Consider the rectangular block of mass m = 28kg, height h = 1.2 m, length l = 0.69 m. A force F is applied horizontally at the upper edge. The acceleration of gravity is 9.8 m/s2. What is the minimum force required to start to tip the block? 2. Relevant equations torque = force x distance net torque = I*angular acceleration So the force diagram would be mg pointing down from the center of mass, which is just the center of the box, normal pointing up from the bottom of the box, and force F pointing right from the top edge. 3. The attempt at a solution Normal force wouldn't provide a torque because right? So it has to do with gravitational torque right? Well, gravitational torque would be mg * 0.6 m (half the height) which equals 164.64 Nm. What do I do from there to find the force needed to tip the box??
