1. The problem statement, all variables and given/known data I have been facing constant problems in solving questions about friction. I wish to formulate a general method of solving such questions. http://img71.imageshack.us/img71/3535/frictionzf3.jpg [Broken] Here u1, u2 and u3 are friction coefficients. (Assume kinetic coefficient to be same as limiting static coefficient ) I wish to find the acceleration in each block in a systematic manner when a force F is applied on block 1) A 2) B 3) C Help me discern a solution in a systematic manner in order that I may remember it for a long time.
