A circular rod of diameter 8 mm and 300 mm long is subjected to a tensile force 20 kN. Take E = 200KN /mm? . Find stress, strain and elongation of the bar due to applied load.

3. A rectangular solid bar of width 20mm and depth 35mm is subject to a pure positive moment of 450Nm. Calculate the stress in the bar and sketch the stress distribution through its thickness along the centre line. 4. The bar in Q3 is also subject to a tensile load of 15kN applied at the centroid of area. Calculate the stress in the bar and sketch the stress distribution through its thickness along the centre line.
