The system is used to lift a block with mass 300 kg. If the friction coefficient between two blocks, and between a block and a surface, are 0.20 and 0.35, respectively, what is the minimum force P required such that the object is about to be lifted? Assume weights of the blocks to be negligible compared to lifted weight. (g=9.81)
