Motion of a screw while going into the wood is an example

Options

A. linear and spin motion
B. rotation and revolution
C. rotation and spin motion
D. rotation and linear motion

Answer

To solve the question about the motion of a screw while going into the wood, we need to analyze the types of motion involved.

### Step-by-Step Solution:

1. **Understanding the Motion of a Screw**:
- When a screw is driven into wood, it does two things simultaneously: it rotates and moves forward.

2. **Identifying the Types of Motion**:
- **Rotational Motion**: This is the motion that occurs when the screw turns around its own axis. As you turn the screwdriver, the screw rotates.
- **Linear Motion**: This is the motion that occurs when the screw moves straight into the wood. As it rotates, it also advances forward into the material.

3. **Combining the Motions**:
- Since the screw is both rotating (around its axis) and moving forward (into the wood), we can conclude that it exhibits both rotational motion and linear motion.

4. **Choosing the Correct Option**:
- Based on our analysis, the correct description of the motion of the screw while going into the wood is "Rotational and Linear Motion".

5. **Final Answer**:
- Therefore, the correct answer to the question is **Option 4: Rotation and Linear Motion**.
