Question:
If a rod tapers uniformly from 30 mm to 15 mm diameter in a length of 350 mm, if it is subjected to an axial load of 5.6 kN and the extension of the rod is 0.025 mm, then the modulus of elasticity of the rod is
If a rod tapers uniformly from 30 mm to 15 mm diameter in a length of 350 mm, if it is subjected to an axial load of 5.6 kN and the extension of the rod is 0.025 mm, then the modulus of elasticity of the rod is
Show Hint
Always use average diameter or integrate when dealing with tapered rods.
