Given g=10 m/sec

A thin metallic rod of Length L and radius of cross-section r rotates with the angular velocity in a horizontal plane about a vertical axis passing through one of its end.

Density of rod is ρ and Young Modulus of elasticity is Y. Breaking stress of the rod is S

Find out the following

a) Find the tension in the rod as a function of distance from the fixed end

b) Find the tension at the fixed end, midpoint and end point of the rod

c) Find the maximum angular velocity with which it can rotate with out breaking

d) Find the total elongation in the rod
