Question

A 5 m long Aluminium tie rod of cross-section 0.20 m × 0.04 m is subjected to a tensile force induced by its self-weight of 21.20 kg/m considering gravitational acceleration of 10 $m/s^2$. If tensile Young's modulus of Aluminium is 70,000 MPa, the maximum tensile strain in the rod is______ $\times \,10^{-6}$ (rounded off to two decimal places).

Answer 1

The correct answer is : 1.80 to 1.90
