The traffic light below consists of a rigid pole and rigid arms. Since the pole and arms are rigid, the force and moment due to the weight of the traffic lights are transferred to the foundation support at point O. The foundation support at O is embedded securely in the ground.

Which of the following most nearly gives the reaction at C if it is temporarily restrained from translation? 3. Which of the following most nearly gives the actual moment at D? a. 2.68 b. 4.82 c. 1.58 d.3.72

he cable of a suspension bridge, shown in Figure, runs over a frictionless pulley on top of each of the towers at A and B and is fixed by tension anchor at D and E. If the cable carries a uniform horizontally-distributed load of 120 kN/m, design the cable and towers. For the cable you will need to select the appropriate material, profile and cross-section to achieve an overall safety against tensile failure equal to 3. For the towers you will need to select the appropriate height, materiel and cross-section to achieve an overall safety against tensile failure equal to 3.

Solve please In the three-pinned arch ACB as shown in figure, the portion AC has the shape UI a parabola with its origin at C, while CB is a straight line. The portion AC carries a uniformly distributed load of intensity 30 kN/m, while the portion CB carries a uniformly distributed load of intensity 18 kN/m. Calculate the normal force, shear force and bending moment at the point D. -4 m 30 kN/m D 9m- 18 kN/m -3m- B 5m-
