4. (6 marks). a. Draw free-body force diagram for each mass. Use standard symbols to designate forces: applied force (F), friction (f), normal force (N), tension (T), weight (W). If necessary, use additional symbols and explain their meaning. All action-reaction pairs of forces must be designated by the same symbol. Use subscripts if many forces of the same type are in action. All surfaces are rough and friction must be included. F m2
