Truss versus Frame versus machine? how do you identify them [statics question]?
Trusses and frames are structures intended for supporting loads, while machines are meant to transmit forcesA truss is a structure made up of straight members which are connected at the joints, and having the joints at the ends of the membersTrusses are used to support roofs, bridges and other structuresThe basic structure is triangular, or trapezoidalFrames are structures often composed of pin-connecting multi-force members ( i.esubjected to three or more forces)Unlike trusses, they are not necessarily rigid e.glinked mechanismsA machine is also composed of pin-connecting multi-force members, but has moving parts and is usually not considered a rigid structureMachines are designed to transmit loads rather than support them e.g a pair of tongsHope that helps!
