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).
A steel wire of 5.65 mm diameter and 50 m length is used for a hoisting crane. The wire is used to vertically lift a weight of 200 kg attached to its lowest end. Assume the Young's Modulus of Elasticity of Steel as \(2 \times 10^5 \, \text{N/mm}^2\) and gravitational acceleration as \(10 \, \text{m/sec}^2\). The elongation of the steel wire (in mm) will be ............ [rounded off to two decimal places].
For a masonry section of width 600 mm with zero tensile strength and a linear stress–strain response, the minimum eccentricity (in mm) at which cracking begins is \(\underline{\hspace{2cm}}\).
A simply-supported steel beam made of an I-section has a span of 8 m. The beam is carrying a uniformly distributed load of 15 kN/m. The overall depth of the beam is 450 mm. The moment of inertia of the beam section is 18000 cm\(^4\). The maximum bending stress in the beam will be \(\underline{\hspace{1cm}}\) N/mm\(^2\) (in integer).
The slenderness ratio of a circular column of diameter 300 mm and effective height 3 m is \(\underline{\hspace{2cm}}\).
