Extension of a Tapered Rod under Axial Load
Given:
- Diameter at one end of the rod (D1) = 30 mm
- Diameter at the other end of the rod (D2) = 15 mm
- Length of the rod (L) = 300 mm
- Axial load applied to the rod (P) = 600 N
- Young's modulus of the material (E) = 2 x 10^5 N/mm^2
To find:
- Extension of the rod (ΔL)
Formula:
The extension of a rod under axial load can be calculated using Hooke's Law, which states that the elongation of a material is directly proportional to the applied load and the material's modulus of elasticity:
ΔL = (P * L) / (A * E)
Where:
ΔL = Extension of the rod
P = Axial load applied to the rod
L = Length of the rod
A = Area of the rod
E = Young's modulus of the material
Area of the Tapered Rod:
The area of a rod with varying diameter can be calculated using the formula for the area of a circle:
A = π * d^2 / 4
Where:
A = Area of the rod
π = 3.14159 (approximately)
d = Diameter of the rod at a specific point
Calculation:
1. Calculate the area of the rod at the larger end:
A1 = π * (D1^2) / 4
2. Calculate the area of the rod at the smaller end:
A2 = π * (D2^2) / 4
3. Calculate the average area of the rod:
A_avg = (A1 + A2) / 2
4. Calculate the extension of the rod:
ΔL = (P * L) / (A_avg * E)
Substituting the given values into the formula:
A1 = π * (30^2) / 4 = 706.8583 mm^2
A2 = π * (15^2) / 4 = 176.7146 mm^2
A_avg = (706.8583 + 176.7146) / 2 = 441.7864 mm^2
ΔL = (600 * 300) / (441.7864 * 2 x 10^5) = 0.0025 mm (rounded to four decimal places)
Hence, the extension of the rod under the given axial load is 0.0025 mm.
Given:
- Diameter at one end of the rod (D1) = 30 mm
- Diameter at the other end of the rod (D2) = 15 mm
- Length of the rod (L) = 300 mm
- Axial load applied to the rod (P) = 600 N
- Young's modulus of the material (E) = 2 x 10^5 N/mm^2

2. Calculate the area of the rod at the smaller end:

3. Calculate the average area of the rod:
A_avg = (A1 + A2) / 2
4. Calculate the extension of the rod:
ΔL = (P * L) / (A_avg * E)
Substituting the given values into the formula:
A1 = π * (30^2) / 4 = 706.8583 mm^2
A2 = π * (15^2) / 4 = 176.7146 mm^2
A_avg = (706.8583 + 176.7146) / 2 = 441.7864 mm^2
ΔL = (600 * 300) / (441.7864 * 2 x 10^5) = 0.0025 mm (rounded to four decimal places)
Hence, the extension of the rod under the given axial load is 0.0025 mm.
