Unformatted text preview: F x = 0 F y = 0 Method of Sections 1) Find the resultant forces with methods from chapter 3 2) Pass a section cut through no more than 3independent unknown forces 3) Draw a F.B.D. of the remaining section with cut member forces acting as applied loads 4) Solve for member forces using the Equilibrium Equations F x = 0 F y = 0 M point = 0 Frames and Machines A Structure with at least one multiforce member To Solve for Member Forces 1) If when removing the supports the structure is still rigid, find the Reactions of entire structure using techniques from Chapter 3. 2) Locate the 2Force members 3) Disassemble the entire structure, and draw F.B.D. of multiforce members. Take special care to properly draw the ActionReaction pairs of forces between connected members. 4) Solve for the member forces using the Equilibrium Equations F x = 0 F y = 0 M point = 0...
