Using the method of joints, determine the force in each member of the double-pitch truss shown. Assume P=1.60 N. Trusses and the Method of Joints: Free Body Diagrams are probably the most important step in solid mechanics, and this especially includes trusses....
economically, trial and error to choose a light weight design for structures and definitely the time needed for doing these works. Therefore, an optimization method capable of having an artificial intelligence technique is severely required. The artificial intelligence method should not evaluate all of ...
Determine the force in each member of the truss shown by the method of joints. For the truss shown, determine the member forces in EF, EG, and FG in pounds. Find the force in member EL, the only member of the truss that has a length other than 1 m. For the truss shown, fin...
The design procedure involves a three-step optimization: (1) compute the multi-compatible structure geometry and stiffness; (2) calculate the MEP by NEB method; (3) design the corresponding actuation. A higher-level loop has been applied on top of the three-step optimization for a more compac...
the numerical results shown inFig. 10portray the features of the FTPD and the M−FTPD method thatPMFTgrows from fast to slow and close toPFTafter3σ, which always remains at the level of 1. Thus,PMFTcan be replaced byPFTwhen the rational range is considered by membership function to ...
A foldable and expandable antenna reflector, and method of making and using the same are disclosed. The antenna reflector includes a reflector and a support structure where the support structure includes a hub assembly; a hub tower extending from the hub assembly; a plurality of drive strut assem...
Examples of special loads might include mechanical units, poultry cages, cranes, sprinkler systems, movable partition walls, etc. The weight, location and method of attachment must be provided to the truss designer. Multiple load cases may be required in truss design. Typical Roof Truss Design ...
The damage detection of a bridge structure based on static tests is to carry out a static load test on the bridge structure under the closed condition of bridge operation and measure the static parameters such as deflection and strain of the bridge under static load. The method of structural ...
This is fine if the gussets are modeled as pure pin-connected, for then a simple Method of Joints or Sections analysis of the axial forces is all that is required under static loading. But if not pin-connected, I must have a way to compute the moments that is less onorous than the ...
