A stone of mass `m` tied to one end of a wire of length L. the diameter of the wire is D and it is suspended vertically. The stone is now rotated in a horizontal plane and makes an angle 6 with the vertical. If Young's modulus of the wire is `Y`, Then the increase in the length of the wire is

A stone of mass m is tied to one end of a wire of length L. The diameter of the wire is D and it is suspended vertically. The stone is now rotated in a horizontal plane and makes an angle θ with the vertical. If Young's modulus of the wire is Y , Then the increase in the length of the wire is

A stone of 0.5 kg mass is attached to one end of a 0.8 m long aluminium wire of 0.7 mm diameter and suspended vertically . The stone is now rotated in a horizontal plane at a rate such that the wire makes an angle of 85^(@) with the vertical . find the increase in the length of the wire . The Young's modulus of aluminium = 7 xx 10^(10) Nm^(-2) , sin 85^(@) = 0.9962 , cos 85^(@) = 0.0872

A stone of mass (m) is attached to one end of a small wire of length (l) and cross-sectional area (A) suspended vertically. The stone is now rotated in horizontal plane such that the wire makes an angle . theta . with vertical. Find the increase in length of wire if its Young.s modulus is Y.

A stone of mass m is attached to one end of a wire of cross-sectional area A and Young's modulus Y. The stone is revolved in a horizontal circle at a speed such that the wire makes an angle theta with the vertical. The strain produced in the wire will be

A stone of mass 1kg is attached to one end of a 1.4 m long aluminimum wire 0.4 mm in diameter and stone is rotated in a horizontal plane at a rate such that the wire makes an angle of 60^(@) with the vertcal. Take Young's modulus of aluminium = 7 xx 10^(10) N//m^(2) . If increase in length of the wire is (2Delta l)/(pi) mm then value of Delta l is :

An iron wire of length 4 m and diameter 2 mm is loaded with a weight of 8 kg. if the Young's modulus Y for iron is 2xx10^(11)N//m^(2) then the increase in the length of the wire is

A wire of mass m and length l is suspended from a ceiling. Due to its own wieght it elongates, consider cross-section are of wire as A ans Young's modulus of material of wire as Y. Th eelongation in the wire is
