Extension due to cone.

Classical Mechanics Level 4

A ring of mass m m , radius R R , cross sectional area A A and Young's modulus Y Y is kept on a smooth cone of radius 2 R 2R and semi vertical angle 45°, as shown in the figure.

Assume that the extension in the ring is small.

What is the extension in the ring?

m g R A Y \frac{mgR}{AY} 2 m g R A Y \frac{2mgR}{AY} m g R 4 A Y \frac{mgR}{4AY} m g R 2 A Y \frac{mgR}{2AY}
