WebTorsional rigidity, sometimes referred to as torsional stiffness, is the ability of an object to resist twisting when acted upon by an external force, torque. In mechanics of materials, torsional rigidity is the resistance to angular deformation a material has. Torsional Rigidity= Applied Torque*Length of ShaftAngle of Twist (Radians) or WebIn a braced frame, this resistance may be used to reduce the mid-span moment and deflection, facilitating the selection of a smaller beam. Costs. Simple connections are invariably cheaper to fabricate than moment-resisting connections, because they involve much less fabrication effort, particularly in welding. WebSpot weld made by resistance welding has been widely used in joining sheet metal of auto body since 1950’s. Every modern car has over 2000 spot welds. Failure of the spot weld is therefore an important concern to auto body durability and safety design. rumors track listing
