3. For structure problems, identify which of the following statements is correct. a) Method of sections is usually used to determine all member forces in a truss. b) Two-force members do not need to be on the same line of action but should equal in magnitude and opposite in sense. c) In truss problem, some member forces are considered to be two-force members. d) The methods of joints and the method of sections can be used together for efficient analysis of a truss. e) The method of joints allows you to solve for up to three unknown forces acting at each joint in a planar truss problem. 4. If there is no external load on a joint, then all the members connected to this joint must be zero-force members. a) True b) False 5. Which one of the following are not characteristics of an ideal truss? a) All members are connected at their ends with smooth pins b) All members act as two-force members. c) Except for the weight of each member, all loads on the truss are applied at the joints. d) Each truss member must be either in tension or in compression. e) None of the listed
