The bar of length 2L, L - 10 m (see the figure) is loaded along its axes with the load 9(2) 120- L -21 The right end is fixed. At the left end, the spring of stiffness k = 200 MN/m connects the bar to the fixed support. It is fully relaxed when no external load fr fo exists. The elastic modulus E200 GPa is uniform, and the cross-sectional area varies as A(x)=100 om 20 The bar of length 2L, L - 10 m (see the figure) is loaded along its axes with the load 9(2) 120- L -21 The right end is fixed.
