## C6-21: SUSPENDED ROD ON WATER

• ID Code: C6-21
• Purpose: An elementary problem involving horizontal friction.
• Description: The top end of a rod is supported by a string connected to a fixed point, with the bottom end floating freely on a small piece of styrofoam on the surface of the water. Which of the three drawings, depicted above, best portrays the equilibrium position of the system: (a), (b), or (c)?
