19. A block of mass m₁ is stacked on top of another block of mass m2 and attached via a massless string (see Fig. 4). The coefficient of static friction between the blocks is µg, and the coefficient of static friction between the block and the surface is us. The pullies are massless and frictionless. What is the maximal mass W of a weight attached to the bottom block that still makes the system stationary?
