A rectangular bar 40 mm wide and 30 mm thick is 0.5 m long. It is acted upon by axial tensile force of 120 KN. Find Change in dimensions of the bar. (E = 200 Gpa and μ=0.25.)
Added by Megan B.
Step 1
\[ A = \text{width} \times \text{thickness} \] \[ A = 40 \, \text{mm} \times 30 \, \text{mm} \] \[ A = 1200 \, \text{mm}^2 \] Show more…

A steel bar 35 mm × 35 mm in section and 100 mm long is acted upon by a tensile load of 180 kN along its longitudinal axis and 400 kN and 300 kN along the axes of the lateral surfaces. Determine (a) Change in dimensions of the bar (b) change in volume (c) longitudinal axial load acting alone to produce the same longitudinal strain as in (a). Take E=205 GPa; μ=0.3.

Two bars, one composed of aluminum and one of steel, are placed end to end as shown in Figure P11.56. The bars are both initially of length $L=25 \mathrm{cm},$ and both have a square cross section with $h=2.0 \mathrm{cm} .$ If a compressive force $F=10,000 \mathrm{N}$ is applied to each end, what is the change in length of each bar?
