### Problem Statement The 5.5-kg uniform rod is pinned at end A. It is also subjected to a couple moment of 50 N⋅m. The spring is unstretched when θ = 0, and has a stiffness of k = 60 N/m. #### Given Data: - Mass of the rod (uniform): 5.5 kg - Moment couple: 50 N⋅m - Spring stiffness, k: 60 N/m - Unstretched condition of the spring at θ = 0 ### Objective: Determine the smallest angle θ for equilibrium. - Express your answer in degrees to three significant figures. ### Input Box: Enter your answer for angle θ in degrees in the given input box. ``` θ = ______________ ∘ ``` ### Figure Explanation: The figure represents a mechanical setup consisting of: 1. A uniform rod (5.5 kg) pinned at end A. 2. A spring with stiffness k = 60 N/m positioned near the rod. 3. The rod subjected to a couple moment of 50 N⋅m. 4. The spring is connected to the rod at point B. 5. The dimensions are: - Length from A to B: 2 m - Spring attachment length from pin A: 0.5 m. The rod is shown with its initial position forming an angle θ with the vertical. The spring is also depicted attached to point B on the rod. ### Instructions: Click the "Submit" button after entering your answer. If you require assistance, use the "Request Answer" button. Provide feedback if needed through the "Provide Feedback" option. --- This text will help students engage with a practical mechanical problem involving equilibrium conditions for a pinned rod and includes the necessary contextual understanding and visual aid for effective comprehension.
