In the system in figure M=13.4 kg, m1=1 kg, m2= 2 kg and m3 = 3 kg. the coefficient of static friction between m1 and m2 is 0.75 and between m2 and m3 is 0.6. all other surfaces are frictionless. what minimum horizontal force F must be applied to M , so that m2 doesn’t slip on M? what maximum value of horizontal force F must be applied for which m1 doesn’t slip on m2? if F=100N , does m1 slip with respect to m2 or m2 slips with respect to M?

  1. what minimum horizontal force F must be applied to M , so that m2 doesn’t slip on M?
  2. what maximum value of horizontal force F must be applied for which m1 doesn’t slip on m2?
  3. if F=100N , does m1 slip with respect to m2 or m2 slips with respect to M?
