H C Verma, Friction, Prob-24, 27: The friction coefficient between the two blocks shown in the fig

Solution, H C Verma, Friction, Prob-24, 27
24) The friction coefficient between the two blocks shown in the figure 6-E9 is µ but the floor is smooth.
a) What maximum horizontal force F can be applied without disturbing the equilibrium?
b) What will be the accelerations of the two masses if the horizontal force is doubled?
27) A block of mass m slips on a horizontal table under the action of a horizontal force applied to it. The coefficient o friction between the block and the table is µ. The table does not move on the floor Find the total frictional force applied by the floor on the legs of the table. Do you need the friction coefficient between the table and the floor or the mass of the table?
