: 2 A Flat Bar With A Cross Section Of 5 0 Mm X 50 Mm Elongates 2 1 Mm In A Length Of 1 5 M As A Result Of An Axial Load 1 (13.05 KiB) Viewed 44 times

2. A flat bar with a cross section of 5.0 mm x 50 mm elongates 2.1 mm in a length of 1.5 m as a result of an axial load of 45 kN. The proportional limit of the material is 240,000 kN/m2. Determine (a) the axial stress in the bar and (b) the elastic modulus.
