Assume that the roller at A is replaced by a slider block having a negligible mass. If the rod is initially at rest, and a horizontal force F is applied to the slider, determine the slider’s acceleration. The coefficient of kinetic friction between the block and the track is μ k. Neglect the dimension d and the 578 ...
