The flat truss in the figure below is under the action of three external loads P, Q and S, and is supported under pins A and B. The weight of the truss is negligible in relation to the applied loads. Read the following statements and then check the correct alternative. 1)the supports provide exactly the amount of links needed to keep the structure in balance 2)the corresponding reactions involve three unknowns that can be determined through equilibrium equations. 3)this is a situation where the rigid body is completely bound 4)reactions are statically indeterminate Alternatives a)Statements 1, 2 and 3 are correct. b)Statements 1 and 2 are correct. c)Only statement 1 is correct.
