A Uniform rod is fixed from top and becomes stretched under its own weight.Then which of the following will be true on its elongation:
a) Diameter at the top is smaller than at the top
b) Diameter at the bottom is larger than that of top
c) Diameter is uniform throughout
d) Dimater becomes smaller than previous one uniformly
I know the answer but i want your views and the way you think...I tried to check it out with the forumla for Young's Modulus and Poisson's Ratio...But I think my description for the right answer wasnt right...so contribute please...
