Problem 19.1 A horizontal force P acts on a cabinet that rests on a floor as shown. The cabinet weighs 120 lbf. It is known that the coefficient of static friction is µ = 0.30 and the coefficient of kinetic friction HK = 0.24. (a) If slipping impends, what is the magnitude of P? (b) If tipping impends, (i) what is the magnitude of P, and (ii) at what point will the resultant floor reaction act? (c) What is the smallest magnitude of P that will cause the cabinet to move? What type of motion will the movement be, i.e., "slip" or "tip"? P 36 inches B G C 24 inches 15 inches
