(a) What is the minimum force of friction required to hold
Chapter 4, Problem 4.58(choose chapter or problem)
(a) What is the minimum force of friction required to hold the system of Figure P4.58 in equilibrium? (b) What coefcient of static friction between the 100-N block and the table ensures equilibrium? (c) If the coefcient of kinetic friction between the 100-N block and the table is 0.250, what hanging weight should replace the 50.0-N weight to allow the system to move at a constant speed once it is set in motion?
