A knuckle pin may fail in

Explanation:

• A knuckle joint is used to connect two rods under tensile load.
• This joint permits angular misalignment of the rods and may take a compressive load if it is guided.
• The automotive engine piston is connected to the small end of the connecting rod by means of a piston pin.
• This is one major application of the knuckle joint.
• The valve rod in a steam engine is connected to an eccentric rod by the Knuckle joint.
