Determine the force and moment reactions at the support A of the cantilever beam subjected to the load distribution shown.

The construction features of a cantilever truss bridge are shown in Fig. Here it can be seen that the center truss CD is suspended by the cantilever arms ABC and DEF. C and D are pins. Determine the vertical reactions at the supports A, B, E, and F if a 15-k load is applied to the center truss.

Analyze the continuous beam loaded and supported as shown using three-moment equation. 1 m A A 2 kN 2 kN 6 kN/m 4 kN/m D 0 B C 4 m 1 m 2 m 1 m 3 m a) Determine the reaction at the roller support, B. b) Determine the reaction the roller support, C. c) Determine the moment at the fixed support, D.
