- Explain the assumplions made in derlving Theory of simple bending
- Describe Core of the section 5 What is the limilation of Euler's theory? ( $5 \times 4=20$ Marks) PART - 3 Module - I
- A sleel bolt of diameler 19 mm passes through a copper lube of inner diameter 24 mm and ouler diameler of 34 mm . The boll has threads of pitch 2.4 mm at ane end. Nul is lurned on the boll through 52 degrees so as to lighten the assembly, Find the stresses developed in the boll and the tube. The len...
