Example 2 Suppose one truck is parked on a bridge as shown in the Figure. The truck weighs 1000 lb which is acting through its center of gravity (CG). The bridge weighs 200 lbs per feet, which is uniformly distributed. We can assume the bridge is rigid. We want to know what will be the reaction forces at the supports of bridge at the two ends 1000 lbe 200 Ib/ft 25 Force? 50 Force? Figure 1
4. The beam AC shown in Figure 4 is supported by two columns AE and BD, and carries a load P (P = 50 kN)、The columns have the same square cross section h xh, Young's modulus E = 2x105 MPa. Determine the minimum dimension h of the cross section such that both columns do not fail in elastic buckling. Use the factor of safety of 1.2 against buckling. Pirn connections are used for ends E, A, and B as shown...

4) A 100 foot long simply-supported bridge girder supports the unfactored loads shown in the figure. The uniformly distributed dead load, wD, includes the self weight of the girder, and is constant along the full beam length. Concentrated live loads, PL, are applied as shown in the figure. a) Draw factored shear force and factored bending moment diagrams in the spaces provided. Show magnitudes at locations A, B, C, D and E on each diagram.(8) PL = 50k PL-50k WD-2.5...
