Tapered bar with end load
The small tapered bar BC has length L=0.1 m and is made of a homogeneous material with Young’s modulus E=10 GPa. The cross sectional area of the bar is slowly varying between A0=160 mm^2 (at B) and A0/2 (at C), as described by the function:

A(x)=A0/(1+(x/L))

The bar is fixed at B and a load P=8kN is applied at the free end C. Determine the total elongation, δ, of the bar. (in mm)
