5.3 Method of Sections – Engineering Mechanics: Statics
The method of sections uses rigid body analysis to solve for a specific member or two. Instead of looking at each joint, you make a cut through the truss, turning the members along that line into internal forces (assume in tension). Then you solve the rigid body using the equilibrium equations for a rigid body: [latex]sum F_x=0;sum F_y=0 ...
