A point mass m is suspended at the end of a massless wire of length l and cross section. If Y is the Young's modulus for the wire, obtain the frequency of oscillation for the simple harmonic motion along the vertical line.

A

`(1)/(2pi)sqrt((LA)/(mY))`

B

`(1)/(2pi)sqrt((LAm)/(Y))`

C

`(1)/(2pi)sqrt((YA)/(mL))`

D

`(1)/(2pi)sqrt((mY)/(AL))`

Text Solution

Verified by Experts

The correct Answer is:
C

(c)`k=(YA)/(L)
therefore f=(1)/(2pi)sqrt((k)/(m))=(1)/(2pi)sqrt((YA)/(mL))`

A point of mass m is suspended at the end of a massless wire of length l and cross-section A. If Y is the Young's modulus for the wire, obtain the frequency of oscillation for the simple harmonic motion along the vertical line. [Hint: If x is the displacement of mass m from the equilibrium position then Y = (stress)/(strain)= (F/A)/(x/l) or F = (YAx)/(l) and this force acts opposite to x. Now proceed as in example 3.
