The formula to calculate the Elongation of Prismatic Bar due to its Own Weight is:
\[ \Delta = \frac{2 \cdot W_{load} \cdot L_{bar}}{A \cdot e} \]
Elongation is the change in length due to the subjected load. Load is the instantaneous load applied perpendicular to the specimen cross-section. Length of Bar is defined as the total length of the Bar. Area of prismatic bar is the amount of two-dimensional space taken up by an object. The Elastic Modulus is the ratio of Stress to Strain.
Let's assume the following values:
Using the formula:
\[ \Delta = \frac{2 \cdot 3600 \cdot 2}{64 \cdot 50} = 4.5 \]
| Load (Wload) | Length of Bar (Lbar) | Area of Prismatic Bar (A) | Elastic Modulus (e) | Elongation (Δ) |
|---|---|---|---|---|
| 3500 | 2 | 64 | 50 | 4.375000000000000 |
| 3550 | 2 | 64 | 50 | 4.437500000000000 |
| 3600 | 2 | 64 | 50 | 4.500000000000000 |
| 3650 | 2 | 64 | 50 | 4.562500000000000 |
| 3700 | 2 | 64 | 50 | 4.625000000000000 |
