Question

A flat bar of rectangular cross section, length L, and constant thickness t
is subjected to tension by forces P (see figure). The width of the bar
varies linearly from b₁ at the smaller end to b₂ at the larger end. Assume
that the angle of taper is small.
(a) Derive the following formula Tor the elongation of the ban
(b) Calculate the elongation, assuming L=5 ft, t=1.0 in., P= 25 kips, ft, =
4.0 in., ft, = 6.0 bland E= 30 x 10⁶ psi.
