Mechanics Homework 8-2 250 - Reaction at the supports of cantilever truss Name_______________ Mr. Haynes Date_______________

Problem 8-2 The cantilever truss shown in Fig. P-250 carries a vertical load of 10.8 kN. The truss is supported by bearing at A and B which exert the forces A v , A h , and B h . The four forces shown constitute two couples which must have opposite moment effects to prevent movement of the truss. Determine the magnitude of the supporting forces.

$$A_v = 10.8 \, \text{ kN upward}$$

$$A_h = 16.2 \, \text{ kN to the left}$$

$$B_h = 16.2 \, \text{ kN to the right}$$
