Conical bar/Prismatic Bar.

= (wl^2/6E) / (wl^2/2E),
=1/3.

Mention the relationship between the weights of both.

Parth said:   8 years ago
It Depends on the weight of both.

Elongation of a conical bar under its own weight is = wl^2/6E.

Prismatic bar = wl^2/2E.

Elongation of bar = (gama)l^2/2E.

Elongation of conical bar = (gama)l^2/6E.
