Here's a problem to review free body analysis. The drawing shows three boxes resting on a horizontal surface. Block A has a rope connecting it to a wall and block B has a force F being applied to it. There is friction between all surfaces. Draw a A separate free-body diagram for blocks B and C. Follow the format that is shown for block A by labelling each force and describing each force using words. Identify any Newton's 3rd law pairs NB T= the tension in the string NB = the normal force of block B on A fg = the frictional force of B on A WA = the weight of A A fg WA
