Deflection of bar under axial loading:
\(δ = \frac{PL}{AE}\)
where P = load, L = length, A = cross sectional area, E = Young's modulus.
Calculation:
Given:
P = 2.4 kN, A = 200 mm2, L = 20 mm, δ = 0.15 mm.
Deflection of bar under axial loading:
\(δ = \frac{PL}{AE}\)
\(0.15= \frac{2.4\;\times\;10^3\;\times \;20}{200\;\times\;E}\)
\(E= \frac{2.4\;\times\;10^3\;\times \;20}{200\;\times\;0.15}=1600\;N/mm^2\;or\;MPa\)
