Question: Draw free body diagrams (FBD) for each case in the hanging potted plant system, and identify the forces acting on each component. a) Plant, soil, and pot b) The cord c) The hook d) The entire system (plant, soil, pot, cord, and hook) Answer: a) The plant, soil, and pot FBD has tension force (\(\overrightarrow{\mathbf{F}}_{\mathrm{t}}\)) acting upward and gravitational force (\(\overrightarrow{\mathbf{F}}_{\mathrm{g}}\)) acting downward. b) The cord FBD has the force exerted by the hook on the cord (\(\overrightarrow{\mathbf{F}}_{\mathrm{hc}}\)) acting upward, and the tension force (\(\overrightarrow{\mathbf{F}}_{\mathrm{t}}\)) acting downward. c) The hook FBD has the force exerted by the ceiling on the hook (\(\overrightarrow{\mathbf{F}}_{\mathrm{ch}}\)) acting upward and the force exerted by the cord on the hook (\(\overrightarrow{\mathbf{F}}_{\mathrm{hc}}\)) acting downward. d) The entire system FBD has the gravitational force (\(\overrightarrow{\mathbf{F}}_{\mathrm{g}}\)) acting downward and the force exerted by the ceiling on the hook (\(\overrightarrow{\mathbf{F}}_{\mathrm{ch}}\)) acting upward.
