Question

can you help me with steps to get the answer below

 

**Question 10.25:** What is the linear speed of the flyweights in Fig. 10.16 if \( L = 20 \text{ cm} \) and \( \theta = 60^\circ \)? What is the frequency of revolution? **Answer:** 1.71 m/s, 1.58 rev/s --- **Explanation of Figure 10.16:** Figure 10.16 illustrates a rotational system with two flyweights each denoted by \( m \) at the ends of rods. Each rod has a length \( L \). The system is rotating around a vertical central axis. Key elements in the diagram include: - **\( \theta \):** The angle between the rod and the vertical axis, given as 60°. - **\( h \):** The vertical distance from the axis of rotation to the line of weights. - **\( R \):** The horizontal radius of rotation, perpendicular to the vertical axis. - **\( v \):** The linear speed of the flyweights. The diagram likely conveys the physical setup needed to solve for the linear speed and frequency of revolution using physics and trigonometry principles. The flyweights are attached to a central point and move in a circular path due to the rotation.
