Consider the stepped bar made with a linear elastic material and subjected to an axial load of 1 kN as shown in figureSegments 1 and 2 have cross sectional area of 100 mm2 and 60 mm2, Young's modulus of 2×105 MPa and 3×105MPa and length of 400 mm and 900 mm respectively. The strain energy in N−mm up to 2 decimal place in the bar due to the axial load is 35 |
