On the horizontal table, there are ten identical little cubes in a row.
The cubes are not bonded together in any way. Squeeze the entire chain with the two outermost cubes in your palms. Which force F should you use to squeeze the cubes off the table and split them apart? Each cube has a mass of m, and the coefficient of friction between cubes is.
"F=10mg\\frac{1+\\mu}{\\mu}."
