In this video I explain how to determine the largest and smallest value a mass must have to prevent a system involving an inclined plane, static and kinetic friction, and a “massless and frictionless pulley” to move at constant speed. I also show how to obtain the maximum and minimum value of the static frictional force required to keep the system at rest. Newton’s laws are applied upon drawing a concrete free-body diagram of each case.
