The heftiest person to cross the bridge is assumed to be 130 kg. Assume that the crossing is simply supported and only one pedestrian can cross at a time. Use modulus of elasticity of timber = 12 GPa. 1. Calculate the maximum flexural stress (MPa). A. 0.114 C. 0.136 B. 0.125 D. 0.156 2. Calculate the maximum shear stress (MPa). A. 0.022 C. 0.016 B. 0.011 D. 0.014 3. Calculate the maximum deflection (mm). A. 0.04 C. 0.10 B. 0.16 D. 0.08 Thanks for watching!
