Answer to Question #338688 in Civil and Environmental Engineering for Jess

Question

A standard HS truck move across a 25 m simple span. The wheel loads are P₁ = 142 kN and P₂ = 142 kN separated by 7.6 m, and P₃ = 36 kN at 4.3 m from P₂.

1. Determine the maximum shear in kN.
2. Determine the maximum moment in kN – m under P₁.
3. Determine the maximum moment in kN – m under P₂.
