Question

In the first image (with the hand) is a stopper attached to a fishing line that is threaded through a glass rod with a mass hanging from it. In the second image, this apparatus is used to produce circular motion in a vertical plane, keeping the stopper moving at a constant speed. Using the second image, draw a free body diagram of the stopper when it is at its highest point and also at the bottom position.

The image shows a hand holding a tube horizontally. Attached to the tube is a string with a weight hanging at the bottom. The top of the tube has a stopper, and the string passes through it. The setup appears to demonstrate a physics experiment related to centripetal force.

Here's a detailed explanation of the setup:

- **Hand and Tube**: The hand is gripping a vertical tube through which a string passes.
- **String and Weight**: The string has a weight attached at the bottom end, while the other end is connected to a stopper above the tube.
- **Circular Motion Indication**: The stopper and string arrangement allow for the demonstration of a circular motion experiment, illustrating concepts like centripetal force.

This setup is typically used to explore the relationship between the force, mass, and speed in the context of circular motion physics.

**Figure 7-11**

This diagram illustrates a pendulum's circular motion and the Free Body Diagrams (FBD) at the top and bottom of the swing.

- **Circular Motion:**
- The pendulum swings in a circular path. The circle represents the motion path, with a dotted arrow pointing inward labeled "r" indicating the radius of the circle from the pivot to the pendulum bob. A vector arrow labeled "v" shows the velocity of the pendulum bob at its current position on the circle.

- **Free Body Diagrams (FBD):**
- **Top Position:** A circle representing the pendulum bob, with a downward dotted line pointing to a solid block indicating the forces acting on the pendulum at the top of its swing.
- **Bottom Position:** Similar to the top position, but the bob is at the bottom of its swing, with a downward dotted line pointing to a block indicating the forces acting at this point.

This diagram helps visualize the forces acting on a pendulum during its swing, emphasizing the differences at the top and bottom positions.

Expert Solution

Step 1

The stopper attached to the fishing line is rotated in a vertical plane, with a constant velocity, in a circular path of radius r.

Any object performing circular motion is acted upon by a centripetal force, which is a necessary force for circular motion.

This centripetal force acts along the radius of the circular path, towards the center, and is given as

$F_{c} = \frac{m v^{2}}{r}$

m is mass of the object

v is its velocity

And along with this centripetal force, the other force acting on the object will be its weight or the gravitational force, acting vertically downwards.
