The supports used to support the truss shown below consist of rollers at 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)although vertical movement is impeded, the truss can move freely horizontally 4)the reactions involve only two unknowns and the lattice is partially linked
