Block Placed on Top of Another Block - Finding Max Force

[QUOTE="drvrm, post: 5464831, member: 527528"] i think your free body diagram needs correction; if the system is moving to the right by say acceleration a , then the top block will experience a frictional force in the forward direction which will [U]oppose the top block being left behind [/U]and [U]if it can not counter it the top one will slip behind [/U]- so there is a limit to the acceleration of the system. the frictional force is always opposed to the tendency of motion of the surfaces in contact. if you take the system as a whole the kinetic friction will be acting opposite to the motion of the blocks at the surface in contact if you consider bottom block separately then its weight will become total weight of the system and the kinetic friction force will oppose it. the reaction of the bottom on the top block will be equal to the wt of the top on the bottom.therefore the bottom will be heavier by addition of the top's weight and total reaction felt by the bottom will be equal to the total weight.mind it action and reaction forces are equal and opposite but act on different bodies .
