A uniform cube of side length 5.9 cm rests on a horizontal floor. The coefficient of static friction between cube and floor is μ. A horizontal pull ?→P→ is applied perpendicular to one of the vertical faces of the cube, at a distance 5.3 cm above the floor on the vertical midline of the cube face. The magnitude of ?→P→ is gradually increased. (a) If μ is less than what value will the cube eventually begin to slide? (b) If μ is greater than what value will the cube eventually begin to tip? (Hint: At the onset of tipping, where is the normal force located?)
