Q. 1.30
Redo Example 1.29 if the beam is supported on springs of stiffness, k = 200 kN/m.
Step-by-Step
Verified Solution
Static deflection of the beam,
\sigma_{s t}=0.0844+\frac{100}{200}=0.5844 mmImpact factor =1+\sqrt{1+\frac{2 \times 500}{0.5844}}=42.38
\delta_{\max }=0.5844 \times 42.38=24.76 mm\sigma_{\max }=0.225 \times 42.38=9.53 MPa
