The 1.69-kg uniform slender bar has a 0.70-kg particle attached to its end. The spring constant is k = 299 N/m and the distance b = 255 mm. If the bar is released from rest in the horizontal position shown where the spring is unstretched, determine the maximum angular deflection 8max of the bar. Also determine the magnitude of the angular velocity at 8 = 8max/2. Neglect friction.

Chapter 6, Problem 6/182 The 1.69-kg uniform slender bar has a 0.70-kg particle attached to its end. The spring constant is k = 299 N/m and the distance b = 255 mm. If the bar is released from rest in the horizontal position shown where the spring is unstretched, determine the maximum angular deflection 8max of the bar. Also determine the magnitude of the angular velocity at 0 = 0max/2. Neglect friction. Answers: 1.69 kg 3b A The maximum angular deflection: max = When 0 = 0max/2: @= B 0.70 kg rad/s
