440:221 Lectures eading Quiz 1. In the method of sections, generally a “cut” passes through no more than _____ members in which the forces are unknown. Reading Quiz A) 1 B) 2 C) 3 D) 4 If a simple truss member carries a tensile force of T along its length then the B) C) 2. If a simple truss member carries a tensile force of T along its length, then the internal force in the member is ______ . A) Tensile with magnitude of T/2 B) Compressive with magnitude of T/2 )p g C) Compressive with magnitude of T D) Tensile with magnitude of T D) School of Engineering, Fall 2009

440:221 Lectures pplications Applications Long trusses are often used to construct large cranes and large lectrical transmission towers electrical transmission towers. The method of joints requires that many joints be analyzed before we can determine the forces in the middle part of a large truss. o we need another method to determine such forces School of Engineering, Fall 2009 So we need another method to determine such forces.
