The bar shown in the figure is made of a single piece of material. It is fixed at one end and consists of two segments of equal length `(L)/(2)` but different cross-section area A and 2A. What is the change in length of the system under the action of an axial force F. [ consider the shape of joint to remain circular, Y is young's modulus]

The bar shown in the figure is made of a single piece of material. It is fixed at one end. It consists of two segments of equal lengh L//2 each but different cross sectional area A and 2A . Find the ratio of total elongation in the bar to the elongation produced in thicker segment under the action of an axial force F . Consider the shape of the joint to remain circular. (Given : Y is Young's modulus.

Y is the Young's modulus of the material of a wire of length L and cross-sectional area A. It is stretched through a length l. What is the force constant of the wire?
