A copper wire of negligible mass, length l and corss-section A is kept on a smooth horizontal table with one end fixed. A ball of mass m is attached to the other end. The wire and the ball are rotating with an angular velocity `omega`. If elongation in the wire is `Deltal`, obtain the expression for the Young's modulus.

A copper wire of negligible mass, length l and corss-section A is kept on a smooth horizontal tabel with one end fiexed. A ball of mass m is attached to the other end. The wire and the ball are rotating with an angular velocity omega . If elongation in the wire is Deltal , obtain the expression for the Young's modulus.

A copper wire of negligilble mas, length (l) and cross-sectional area (A) is kept on a smooth horizontal table with one end fixed, a ball of mass 'm' is attached at the other end. The wire and the ball are rotated with angular velocity 'omega' . If wire elongates by Delta l then the Young's modulus of wire and if on incresing the angular velocity from omega to omega^(1) when the wire breaks-down, then the brekaing stress (Deltal lt lt l ) are respectivley.

A copper wire of negligible mass, 1 m length and cross-sectional area 10^(-6) m^(2) is kept on a smooth horizontal table with one end fixed. A ball of mass 1 kg is attached to the other end. The wire and the ball are rotating with an angular velocity of 20 rad//s . If the elongation in the wire is 10^(-3) m . a. Find the Young's modulus of the wire (in terms of xx 10^(11) N//m^(2) ). b. If for the same wire as stated above, the angular velocity is increased to 100 rad//s and the wire breaks down, find the breaking stress (in terms of xx 10^(10) N//m^(2) ).
