Strength of Material Important Questions

UNIT - 1 SIMPLE STRESSES & STRAIN 1.A load of 5 KN is to be raised with the help of a steel wire. Find the diameter of steel wire, if the maximum stress is not to exceed 100 MN/m2.[ 7.28 mm] 2.A circular rod of diameter 20 m and 500 m long is subjected to tensile force of 45kN. The modulus of elasticity for steel may be taken as 200 KN/m2. Find stress, strain and elongation of bar due to applied load.[ 143.24 N/m2, 0.000716, 0.36] 3.Find the minimum diameter of the steel wire, which is used to raise a load of 4000N if the stress in the rod is not to exceed 95 MN/m2 . [d=7.32 mm] 4. Find the young modulus of a brass rod of diameter 25mm and of length 250mm which is subjected to a tensile load of 50kN when the extension of the rod is equal to 0.3mm. [E = 84.88 X 109N/m2] 5.A hollow cast-iron cylinder 4 m long, 300 mm outer diameter, and thickness of metal 50 mm is subjected to a central load on the top when standing straight. The stress produced is 75000 kN/m2. Assume Young's modulus …
