Meriam, Kraige & Bolton — Plane Kinetics of Rigid Bodies: Problem 6_182

*6/182 The 1.2-kg uniform slender bar has a 0.6-kg particle attached to its end. The spring constant is \( k = 300 \, \text{N/m} \) and the distance \( b = 200 \, \text{mm} \). If the bar is released from rest in the horizontal position shown where the spring is unstretched, determine the maximum angular deflection \( \theta_{\text{max}} \) of the bar. Also determine the value of the angular velocity at \( \theta = \theta_{\text{max}}/2 \). Neglect friction.
