Static deflection of the beam,

σst=0.0844+100200=0.5844 mm\sigma_{s t}=0.0844+\frac{100}{200}=0.5844  mm

Impact factor =1+1+2×5000.5844=42.38=1+\sqrt{1+\frac{2 \times 500}{0.5844}}=42.38

δmax⁡=0.5844×42.38=24.76 mm\delta_{\max }=0.5844 \times 42.38=24.76  mm

 

σmax⁡=0.225×42.38=9.53 MPa\sigma_{\max }=0.225 \times 42.38=9.53  MPa
