Please I need help. I hope you can help.  A 25 m simply supported girder of a bridge is used to support the moving axle loads of 150 kN and 45 kN. Use d = 4.30m. a. Calculate the maximum support reaction in kN b. Calculate the maximum shear at midspan in kN c. Calculate the maximum span moment in kN-m.

9-3. Determine the reactions at the supports, then draw the moment diagram. The moment of inertia for each segment is shown in the figure. Assume A and C are rollers and B is a pin. Take E = 200 GPa. 6. B. 40 kN 20 kN 20 kN IAB = 120(10°) mmLD IBC = 90(10°) mm %3D -3 m 3 m -3 m- -4 m- 4 m- iq s zi 8 omua2A 2noiloco högqua on nimmote Jns Prob. 9-3olloT o bms A brs

The hoist supports the 150-kg engine. Determine the force in members DB and FB. Also determine the reactions on the floor at A and C. m m 2 m BO E 2 m 1m

In the plane truss system, whose loading condition is shown in the figure, there will be support reactions A and B, and rod forces 1,2 and 3. 8- Ais the fixed joint and B is the sliding joint.
