Skills for analyzing situations using equilibrium conditions

A uniform cubical 200-kg box sits on the floor with its bottom left edge pressing against a ridge. The length L of a side of the box is 1.2 m. Determine the least force you need to exert horizontally at the top right edge of the box that will cause its bottom right edge to be slightly off the floor, as shown in Figure P7.49. (Note: With the right edge slightly off the floor, the ground and ridge exert their forces on the bottom left edge of the box.)
