Extension of Tapered Bar (Cone Frustum) due to its Self weight and applied Load (Solved Example)

Hi,

Problem: A uniformly tapered bar of steel 500m long is suspended vertically and supports a land of 1KN attached to the lower end. The bar has a circular cross-section with a diameter of 10 mm at the lower end and 20 mm at the upper end.
Find the total extension of the bar due to its own weight and the suspended load. Take the specific weight of steel as
80 kN/m3 and E=210 GPa.


Solution:


If you find any doubt or any problem with the solution, please leave a comment or suggestion.

Thank you!
