Problem B15:
One block, mass m0, sits on top of another block which has a mass of
n1m0. The bottom block is on the floor, and there is
no friction between the floor and the bottom block. The coefficient of static friction
between the top block and the bottom block is &mu = 1/n2. A force
F pulls to the right on the bottom block. What is the maximum force Fmax
that the force F can have such that the top block does not slip off the bottom block?
If Fmax = n3m0g,
what is n3? Note that n1, n2 and n3 are
unitless.
