Question
![**Problem Statement:**
Q13. The collars are pin connected at \( B \) and are free to move along rod \( OA \) and the curved guide \( OC \) having the shape of a cardioid, \( r = \left[ C \cdot (1 + \cos \theta) \right] \, \text{m}, \) where \( C = 0.2 \). The rod \( OA \) moves at a constant angular velocity \( \dot{\theta} = 2.9 \, \text{rad/s} \). Determine the magnitude of the velocity of the collars at the instant \( \theta = 0.9 \, \text{rad} \). Please pay attention: the numbers may change since they are randomized. Your answer must include 3 places after the decimal point, and proper SI unit.
**Diagram Explanation:**
The diagram shows a structure with a rod \( OA \), which rotates about point \( O \). The point \( A \) is connected to collars, which move along both the rod \( OA \) and a cardioid-shaped path \( OC \). The angle \( \theta \) is defined between the rod \( OA \) and a horizontal reference line, with the direction of the increasing angle shown by an arrow. The cardioid path \( OC \) is represented by a curve, and the radius \( r \) is labeled from point \( O \) to point \( C \). The collar at \( B \) is marked on this setup.
**Input Fields:**
- **Your Answer:**
- A field labeled 'Answer' for numerical input.
- A field labeled 'units' for the unit of measurement.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd1b995ae-802e-43da-9ee9-b523df7a22af%2F6faf177f-6194-4e69-8a91-3c77adda2b0e%2Flzk55ma_processed.jpeg&w=3840&q=75)
