Question

A rod hinged at one end is released from the horizontal position as shown in the figure. When it becomes vertical its lower half separates without exerting any reaction at the breaking point. Then the maximum angle ‘theta’ made by the hinged upper half with the vertical is :

  1. 30°    
  2. 45°    
  3. 60°    
  4. 90°    

The correct answer is: 60°
