Pinned Joint Model

Model consists of hinged joints. Model will be able to demonstrate the qualitative behavior of the truss under load. As the members are very flexible, a compression member will easily show it's buckling i.e. it will curve out of plain. The tension member however remains straight and tight. The student will therefore have a visual picture of the type of stresses i.e. compressive or tensile that each member of truss will carry under various positions of the load. In case of pinned joint truss, the student will be able to observe that angle between members at each joint undergo a small change
