# SS-V: 1050 Tapered Solid Bar

Test No. VS06 Determine the maximum axial deflection and axial stress at the mid-length for a tapered solid bar.

## Definition

A tapered bar of square cross section (Figure 2), is subjected to axial load applied to the end of the bar (Figure 1).

The load is uniformly distributed at the free end of the bar. The other end is fixed.

The units are IPS.

The material properties are:

**Properties****Value**- Modulus of Elasticity
- 10.4e+6 psi
- Poisson's Ratio
- 0.3

## Results

The following table summarizes the
deflection and stress results.

Theory | SimSolid | % Difference | |
---|---|---|---|

Maximum Axial Deflection [in] | 4.8080E-03 | 4.8313E-03 | 0.48% |

Axial Stress* at Midpoint [psi] | 4.4440E+03 | 4.4279E+03 | -0.36% |

*Stress-Z along length of bar. Value take off midpoint of XY graph.
