The maximum value of mass of block C so that neither A nor B moves is (given that mass of A is 100 kg and that of B is 140 kg. Pulleys are smooth and friction coefficient between A and B and between B and horizontal surface is m= 0.3) (Take g = 10ms^-2 ).

Maximum friction that can be obtained between A and B is $$f1=$$μ$$mAg=$$ $$0.3$$ $$100$$ $$10=$$ $$300$$ N and maximum friction between B and ground is $$f2=$$μ$$mA+$$ $$mBg=$$ $$0.3100$$ $$+$$ $$140$$ $$10$$ $$=$$ $$720$$ NDrawing $$free-body$$ diagrams of A, B and C in limiting caseEquilibrium of A gives $$T1=$$ $$f1=$$ $$300NEquilibrium$$ of B gives $$2T1+$$ $$f1+$$ $$f2=$$ $$T2$$ or $$T2=2300$$ $$+$$ $$300$$ $$+$$ $$720$$ $$=$$ $$1620$$ Nand equilibrium of C gives $$mCg=T2or$$ $$10mC=$$ $$1620$$ or mC $$=$$ $$162$$ kg
