A steel rod of 1 sq cm. The cross-sectional area is 100 cm. long and ...
The elongation of the bar is directly proportional to the tensile force and the length of the bar and inversely proportional to the cross-sectional area and the modulus of elasticity. = length of bar (in.) A = cross-sectional area of bar (in.2) d = total elongation of bar (in.)

Calculation of Elongation of Steel Rod Under Axial Pull
Given data:
- Cross-sectional area of the steel rod = 1 sq cm = 100 cm^2
- Length of the steel rod = 100 cm
- Young's modulus of elasticity of the steel rod = 2 x 10^6 Kgf/cm^2
- Axial pull on the steel rod = 2000 kgf
Formula used:
- Elongation (δ) = (F × L) / (A × E)
where,
- F = Axial pull on the steel rod
- L = Length of the steel rod
- A = Cross-sectional area of the steel rod
- E = Young's modulus of elasticity of the steel rod
Substituting the given values in the formula, we get:
- Elongation (δ) = (2000 × 100) / (100 × 2 × 10^6)
- Elongation (δ) = 0.05
Therefore, the elongation of the steel rod under the axial pull of 2000 kgf is 0.05 cm or 0.05 units. Hence, the correct answer is option A, i.e., 0.05.
