A steel bar 10 mm in diameter and 150 cm long is stressed by a weight of 12 kg dropping freely through a height h = 50 mm on to a collar produced at end of the bar, the other end of the bar is fixed to the ceiling. Find the instantaneous stress and instantaneous elongation. Comment whether the bar will break under this shock (impact) load. E 210 kN/mm2, ultimate strength of the steel is 450 MPa. What will be the stress and elongation if the same load is applied suddenly instead of impact loading? A steel rod is placed coaxially in an aluminium tube of outer diameter 60 mm inner diameter 30 mm. A compressive force is applied on assembly as shown in the fig. Deternmine the stresses developed in steel rod and aluminium tube. Use E, = 3E, = 210 GPa. 2. P= 100 kN (3) Alumin Stpel Rod 3.
